Answer:
-4+7h
Step-by-step explanation:
D. the county collects donations to build a fountain in city hall.
B, the $1.50 is a fixed number, but the additional $0.75 varies on how many miles travelled (x).
I assume by starting value, you mean y-intercept. The y-intercept is 15
To find this, we need to use slope intercept form and the given information to find it.
y = mx + b ----> plug in the known values
9 = -3/4(8) + b
9 = -6 + b
15 = b
Therefore, the starting value is 15.
