Mr. Dodson is having the exterior of his house painted. The painters charge
$55 per hour plus the cost of materials
After 20 hours of work, Mr. Dodson
owes the painters $840. Assume the
relationship is linear. Find and
interpret the rate of change and the
initial value.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
