question

What is the slope of this line?

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

key idea

The slope of a line tells you how steep it is. To find the slope, divide the change in

-coordinates

by the change in

-coordinates

between any two points on the line.

slope

change in y

change in x

solution

You can use any two points on the line to find the slope. For example, you can use

(

)

and

(

)

Find the change in

-coordinates

and the change in

-coordinates.

Divide the change in

-coordinates

by the change in

-coordinates

to find the slope.
