Question

Picture shown!

Find the slope of the line represented
by the data below.

Simplify completely.
Slope = [?]
Change in y
Hint: The slope of a line is the
Change in y/Change in X

Answer 1

`slope = - 3`

Explanation:

The slope is given by the formula:

`slope = (change \: in \: y)/(change \: in \: x)`

We can choose any two points in the table to find the change y and change in x .

Note that the order is very important.

`slope = (15 - 9)/(0 - 2)`

Simplify to get:

`slope = (6)/( - 2) = - 3`
