If you are trying to find the slope of a line that is perpendicular to another line, you would need to change the sign and change it to the fraction's reciprocal.
m = 
Change the sign of the slope:
Finally, make the reciprocal of the original slope (switching the numerator and denominator):
Simplify:
3
Final answer:
Step-by-step explanation:

Step-by-step explanation:
36÷3= 12
3 rolls of carpet
the square footage of 40ft*60ft=2,400
