Question

Find the slope of the following graphs.

A. 1/2
B. 2
C. –2
D. –1/2

Answer 1

C) -2

Explanation:

Slope: The slope of the line is the m in the equation for the line:

`y=mx+b`

To find the slope of a line, we use the formula:

`(rise)/(run)`

The rise being units up or down, and the run being units left and right from 1 solid point to another.

In this case, let's use the 2 points (-1,4) and (0,2)

The rise from the first point to the second point is -2 units down, and the run is 1 unit right.

Meaning, once we substitute:

`(-2)/(1) \\=-2`

The slope of this line is -2.

Hope this helps :)
