Question

Write an equation of the form y = mx for the line shown below.

Answer 1

y = -3x

Explanation:

To get slope intercept, you divide both y values by both x values like this

`(y_2 - y_1)/(x_2 - x_1)`

In this case this will be
`((-3 - 6))/((1 - (-2)))`

This will become
`(-9)/(3)`

Divide those two to get -3, and now you get your slope intercept.
