Question

Write an equation in pointslope form for the line that pouze rough each point with the given stopeCONSTRUCTION A construction company charges S15 per hour for debris removal, plus a one time fee for theof a frash dumpster. The total fue for hours of service is stosa Write the point slope form of an equation to find the total fee y for any number of hoursb. Write the equation in slope intercept formthe fire for the use of a trash dumpster?

Answer 1

$15 per hour

For 9 hours the total cost is $195

Total Cost = One time fee + $15 per hour times the number of hours

If y is the total cost and x is the number of hours, we can write:

y = One time fee + 15x

They say that when x = 9, y = 195:

195 = One time fee + 15(9) = one time fee + 135

One time fee = 195 - 135 = 60

One time fee = 60

So the equation would be:

y = 60 + 15x

Th standard form of a line in point and slope is y = mx + b

In this case: y = 15x + 60

Answer:

y = 15x + 60
