Question

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

Answer 1

Slope: 0

Explanation:

The formula to finding slope is
`(y1-y2)/(x1-x2)`

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

So plug in:

`(-4-(-4))/(4-9)`

Simplify:

`(0)/(-5)`

Slope: 0

Answer 2

Explanation:

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

`m = (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 = (y2 - y1)/(x2 - x1)`

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

`m = ( - 4 - ( - 4))/(9 - (4))`

Simplify.

`m = 0`

Therefor, The slope is 0.
