Interpreting Graphs

What does a slope of 2/3 mean? Develop an understanding of the key features of a linear function. Pupils graph the linear functions and explain the meaning of the slope and intercepts of the graphs. 

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to word problems that are more complicated.

Plot a course to learn about plotting linear equations. By watching a short instructional video, pupils learn how to graph a linear equation given in slope-intercept form. The example in the video involves a positive slope and a positive...

Parameters can move and change the steepness of a graph. Introduce the effects of changing the slope or the y-intercept of a linear graph. The resource shows how to incorporate changes on graphs and how they will move up, move down,...

Sometimes a graph makes situations much easier to see. After learning about discrete and continuous graphs by watching a short video, scholars match graphs to real-world situations. The provided graphs are a discrete linear graph, a...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

Graph a linear equation by creating a table to get some values to plot. Select some values for x and plug them into the equation to get the y values. The x and y values make ordered pairs that can be plotted on the graph. After plotting...

With so many types of graphs, don't let your learners get stuck figuring out which one to use. To track how Zoe spent her allowance, use this interactive lesson to review all the types of graphs and pick the best one to display the data....

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

Use this series of activities to introduce learners to graphing functions. They graph both linear and quadratic equations by hand and with a Graph Sketcher Tool. Several imbedded links and handouts are included in the instructional...
