Answer:

y=3x-2

Explanation:

Since we already know the slope, all we need to find is the y-intercept

The equation for a line is:

y=mx+b where m is the slope and b is the y-intercept. x and y are the x and y coordinates. We can use the numbers given in the problem and plug them into the equation...

y=mx+b

-8=3(-2)+b

-8=-6+b

b=-2

So the equation would be...

y=3x-2
