To find the rate of change (slope), we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (2, 22) and (8, 25):
m = (25 - 22) / (8 - 2)
m = 3 / 6
m = 0.5
So, the rate of change is m = 0.5.
To find the initial value (y-intercept), we can use the formula y = mx + b and substitute one of the points:
22 = 0.5(2) + b
22 = 1 + b
b = 21
The initial value is b = 21.
