Question

using point slope formula how do you graph y-2=-3(xt2)

Answer 1

If that equation means

y-2=-3(x+2)

then the point-slope form is just

(y-2)/(x+2) = -3

That makes the point (-2,3) act like the origin: x+2 = 0 and y-3 = 0

Transforming back, you have

(y-3) = -3(x+2)

That means that every time x increases by 1, y decreases by 3 (the slope). Plot a couple of points and draw a line through them.
