For two months, Martin used the same snow removal company to help clear his property. The company had a fixed reservation rate per month, plus an hourly rate for the amount of time that is spent clearing
snow. Martin received two bills from the snow removal company. The first bill was $170 for 4 hours of
snow removal and the second bill was $220 for 6 hours of snow removal. Find the equation of the line
that represents the snow removal company's fixed reservation rate and charge per hour. Round to the nearest cent if necessary.

the answer is 1/4

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
