Sal takes viewers through another example of graphing rational functions "because you really can't get enough practice here." Combined with the two previous videos on graphing rational functions and asymptotes, viewers will walk away with a strong grasp on the concept and its process.
Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.
In this short video, Sal shows how to graph a line in slope-intercept form.
Looking for a resource that goes beyond just graphing inequalities? Here is one that addresses the need to have learners reason and develop a deeper understanding of the solution set of systems of inequalities. This include writing inequalities, analyzing them algebraically, analyzing them graphically, and also through the use of charts. 
The equations look different, but their graphs are the same. How can that be? This activity leads your mathematicians in an exploration of three different forms of the same quadratic function. After comparing the equations, their graphs, and key points on the graphs, learners determine the advantages of using one form for identifying intercepts and a different form for identifying coordinates of the vertex. In addition to the exploration, the activity includes five exercises in writing a quadratic equation whose graph satisfies certain conditions.
Match the graph with its function in an exercise that focuses on variations of the graph of ye^x. Learners are given four graphs on the same set of axes and four functions, all involving e^x. The task is to match each function with its corresponding graph and explain the rationale for each match. An additional focus of this activity is to provide exposure to functions that are used in logistic growth models. The exercise can be used for instruction or assessment.
Get to know your class and teach about data analysis all with the help of Google Docs. Using student-generated questions, create a class survey using Google Forms. Reserve time in the computer lab for learners to complete the form and, amazingly, Google will compile and graph the responses automatically! Display and discuss the results as a whole class, making comparisons and answering questions about the data. A great activity for the first week of school that uses technology to engage children in learning about math.
Have your class investigate the properties of exponential functions and transformations with an activity. Practice evaluating exponential functions and graphing by hand and calculator. Discuss the similarities and differences of graphs with different bases and the effects of transformations on the range, intercepts, and asymptotes. 
Prairie potholes are dips in the earth that contain water, which is vital to the survival of many prairie inhabitants, including the Mallard Duck. Middle schoolers analyze data on the disappearance of these potholes in relation to the mallard duck population. They are given several passages to read as well as several data tables that show changes to potholes, prairie lands, and duck breeding activity. They will create graphs that show each data table and then discuss the relationships they see through data analysis.
The skill set for this lesson is to have learners use tables to generate functions and functions to generate graphs. They work through a series of worksheets with the instructor to determine absolute value, domain, x and y intercept and complete transformations. All of the necessary worksheets and a homework assignment is included.
Ready to introduce your class to the coordinate plane? This website includes a detailed lesson plan that includes two interactive games to help learners practice graphing ordered pairs. The scripted discussion is a little cheesy and a little more direction might be necessary for the games, but would be an easy way to practice graphing online.
This activity consists of three exercises in which learners sketch the graphs of various power functions on the same axes. They use their sketches to make comparisons and observations which lead to generalizations about the graphs of power functions. To aid them in their exploration, students compute specified function values at key points and find points of intersection of the graphs. The graphs can be sketched by hand or with the use of a graphing calculator.   
Algebra learners explore the vertex form of a quadratic equations. They use their graphing calculator to explore transformations of the parabola, and find minimum and maximum values.
After making a correction to the last problem in his previous video, Sal explains how to graph quadratic functions. Those who have a hard time with the concept of graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at textbooks.
In this acceleration worksheet, students use graphs of velocity versus time and acceleration versus time to describe the motion of objects.
Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.
Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.
If your class struggles with graphing inequalities, or if your lecture could use some help from Sal, this video would be a great help. Sal's instruction is measured and patient, and viewers will walk away feeling more confident and successful in their graphing skills.
Sal takes viewers through another example of graphing rational functions "because you really can't get enough practice here." Combined with the two previous videos on graphing rational functions and asymptotes, viewers will walk away with a strong grasp on the concept and its process.
First taking viewers through the process of graphing using intercepts, Sal then works to graph a word problem. His process is so fluid and easy to understand that all mathematicians, beginning and advanced, could benefit from watching his methods.
