y=-8/3+6

Explanation:

Using the slope formula: (y2 - y1)/(x2 - x1)
You should choose the first coordinate point to be (x1, y1) and the other to be (x2, y2)
So (-2 - 6)/(3 - 0) will give you the slope m
Now you need to put the slope and one of the given points into slope-intercept form.
if m=-8/3 you can solve for b in y=mx+b
Inserting the point (0, 6) we get
6=-8/3(0)+b
So, b=6
You can check this using the other point and plug in b.
-2=-8/3(3)+6?
Yes, because this equation is true, b=6 must be the correct y-intercept.
Therefore, our equation is y=-8/3+6
