Question

If the cost of 2 tickets is $32 and the cost of 5 tickets is $80. what is the rate of change and the equation

Answer 1

The rate of change is 19.

Explanation:

To find the rate of change, we will do (y2-y1)/(x2-x1). In this problem, x1=2, y1=32, x2=5, and y2=80. So, (80-32)/(5-2) becomes 57/3 or 19.
