Question

Find the slope of the line from two given points: (12,-18) and (-15,-18)

Answer 1

The answer is 0

Explanation:

use the slope formula!

`m= (y_(2)-y_(1))/(x_(2)-x_(1) )`

12 is xsub1

-18 is ysub1

-15 is xsub2

-18 is ysub2

now solve!

`m= (-18-(-18))/(-15-(12))\\=(0)/(3) \\=0`

slope is 0.

hope this helps!

Answer 2

The slope of the line is 0. It's a horizontal line.

Explanation:

Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

`\displaystyle m=(y_2-y_1)/(x_2-x_1)`

We are given the points (12,-18) (-15,-18).

Calculate the slope:

`\displaystyle m=(-18-(-18))/(-15-12)`

`\displaystyle m=(-18+18)/(-27)`

`\displaystyle m=(0)/(-27)=0`

The slope of the line is 0. It's a horizontal line.
