Linear 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 more complex word problems.

The third example's the charm. Young mathematicians watch a helpful video that shows how to graph a linear equation in slope-intercept form on a coordinate plane. The narrator works through the example y = –2x + 5 by first plotting the...

It makes sense that it's called the slope-intercept form. After reviewing how the slope and y-intercept affects the graph of a linear equation, individuals learn how to graph a linear equation given in slope-intercept form. They watch as...

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...

Let the class stars shine. Using four given linear equations, scholars create a graph of a star. The pupils use the interactive to graph the linear systems and determine the points of intersection. Through the activity, classmates...

How can you graph lines that don't seem to fit on the given graph? What makes a line straight? What does the rate of change mean when graphing a line? How do you know if a slope is positive or negative? How do you know if the graph of a...

Pre-algebra protégés critique a graph depicting Tom's trip to the bus stop. They work together to match descriptive cards to distance-time graph cards and data table cards, all of which are provided for you so you can make copies for...

Given a linear equation, find the x-intercept and the y-intercept to graph the line. Not sure what to do or where to start? Watch this video and see the instructor break it down and make it understandable.

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...

Max out heart rates for males and females. Formulas of maximum heart rates provide the equations for a linear system. Pupils use the interactive to graph the equations for males and females and determine their points of intersection. The...
