we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by
both sides


the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have



substitute the value of m1

therefore
<u>the answer is</u>
the slope is 
So you didn't put an actual question. To find the money he makes you just plug in the numbers.
If he works 4 shifts at the theater you replace x with 4. Then, you find 85 x 4. You do the same thing with 15y.
