Answer:
The rate of change is 3. Y increases by 3 for every 1 increase in x.
Explanation:
See the attached graph.
The rate of change is the slope of the equation y = mx + b
b is the y-intercept, which we find at (0,65).
m, the slope, is 3. The rate of change between the given x points (1,2,3,4,5) is 3. Y increases by three at each step, starting with the y-intercept value of 65.
