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

Answer:
y = -3x
Step-by-step explanation:
To get slope intercept, you divide both y values by both x values like this
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]
This will become [tex]\frac{-9}{3}[/tex]
Divide those two to get -3, and now you get your slope intercept.
