Answer 1

Initial value

b=1,200

Rate of change is the difference in the charge amount per year:

m = (1,350 - 1,200) / (8 - 5) = 150 / 3 = 50

The equation would be:

y = 50x + 1200

Answer 2

Explanation:

Initial value is the y-intercept:

• b = 1200

Rate of change is the difference in the charge amount per year:

• m = (1350 - 1200) / (8 - 5) = 150 / 3 = 50

The equation would be:

• y = 50x + 1200
