Question

A construction company charges $15 per hour for debris removal, plus a one-time fee for the use of a trash dumpster. The total fee for 9 hours of service is $195. Write the point-slope form of an equation to find the total fee y for any number of hours x.( Hint: use the point (9 ; 195

Answer 2

The point-slope form of an equation is y=15x+60.

To find the total fee y for any number of hours x.

What is slope?

Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.

Given that:

We have a function where the total fee, y, that equals an hourly fee of $15 per hour (x hours) and a one-time fee, f,

So what we know at this point is:

y=15x+f

Once we know f, we'll have the equation. But we can solve for f by dropping in the charge for 9 hours:

195=15(9)+f

f=195−135

=60

So we can find the general formula for y:

y=15x+60

So, the point-slope form of an equation is y=15x+60.
