Question

Someone help me please

Answer 1

Answer:

4 (C)

Step-by-step explanation:

Slope (m) = Rise/Run (Change in y/Change in x)

This formula is the same as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's go through each variable.

m is the slope, what we are trying to find.

y2 is the second value of y, 122 ft.

y1 is the first value of y, which is 68 ft.

Finally, we know that x2-x1 is the same as the change in x. The problem tells us that the roof goes over a horizontal distance of 4.5 yards. In this case, we don't need to know x2 and x1. We already know the change in x, so we add that to our formula. Here's what we have so far:

$m= \frac{122-68}{13.5}$

*note that 4.5 yards = 13.5 feet

The slope of the roof is 4.
