Answer:
rate of change = 2 unit rise per 1 unit run
Step-by-step explanation:
The rate of change of two points on a graph is represented by the slope of a line connecting the two points.
here we are given the coordinates of the two points, hence we can simply apply the slope formula for a line given two points (see attached)
for points (0,3) and (2,7)
x₁ = 0, y₁ = 3, x₂ = 2, y₂ = 7
substituting these into the formula
rate of change
= slope, m
= (y₂-y₁) / (x₂-x₁)
= (7 - 3) / (2 - 0)
= 4 / 2
= 2
