Lesson goal: Plotting lines

Previous: Make it snow | Home | Next: Graph the absolute value

After plotting points in your math class, you often move to plotting lines. The "slope-intercept" form of a line is $y=mx+b$, where $m$ is the slope of the line and $b$ is the y-intercept.

Now you try. Set the m and b here and plot some lines!

This code will not run. You have to fix the m= and b= lines to be set to a slope and a y-intercept first. Choose some values! How about 1 and -3? Dismiss.
