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?
Systems of equations are used to solve applications when there is more than one unknown and there is enough information to set up equations in those unknowns.
