A coordinate plane showing the Speed of a Red Kangaroo. The x-axis shows Time in seconds and the y-axis shows Distance Traveled
in feet. There is a straight line with a positive slope starting at (0, 0) and passing through point A at (3, 150), then point B at (4, 200) and continues through (7, 350). Red kangaroos can reach speeds up to 50 feet per second. Use the linear graph at the left to answer the questions.
What is the change in y-values from
Point A to Point B?
What is the change in x-values from
Point A to Point B?
What is the rate of change of the linear function?
Slope intercept form is y=mx+b, with m being the slope and be being the y intercept, so when you look for what b is in the equation for y=-3x+6 then 6 is b.
