Question

find the slope of line through points (4,-4) and (9,-4)

Answer 1

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.

$m = \frac{change \: in \: y}{change in \: x\: }$

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

$m = \frac{y2 - y1}{x2 - x1}$

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{ - 4 - ( - 4)}{9 - (4)}$

Simplify.

$m = 0$

Therefor, The slope is 0.

Answer 2

Answer:

Slope: 0

Step-by-step explanation:

The formula to finding slope is $\frac{y1-y2}{x1-x2}$

We have the points (4,-4) and (9,-4)

So plug in:

$\frac{-4-(-4)}{4-9}$

Simplify:

$\frac{0}{-5}$

Slope: 0
