Question

The pitch of a roof is found the same way as the slope of a line. What is the pitch of a roof that has a height of 9 ft and a horizontal run of 7?

A) 1/2
B) 2/3
C) 3/2
D) 9/7

Answer 1

I'm assuming that the pitch of this roof is in fact its slope...

Slopes are basically tangents...

tan(x)=Opposite/Adjacent

-------

tan(x)=9/7

-------

This means that the answer is D), 9/7.

Answer 2

Answer:

D. $\frac{9}{7}$

Step-by-step explanation:

We have been given that the pitch of a roof that has a height of 9 ft and a horizontal run of 7.

We know that slope of a line represents the relation between rise over run. The run is the horizontal distance between to x-coordinates and rise is vertical distance between two y-coordinates.

$\text{Slope}=\frac{\text{Rise}}{\text{Run}}$  

$\text{Slope}=\frac{9}{7}$  

Therefore, the pitch of roof is $\frac{9}{7}$ and option D is the correct choice.
