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