You can put this solution on YOUR website! (3,4), (-3,2)
first we need to find the slope:
(y2-y1)/(x2-x1)
(2-4)/(-3-3)
-2/-6
1/3 is the slope.
Y=mX+b
4=1/3*3+b
4=1+b
b=4-1
b=3
Y=X/3+3
 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, x/3 +3).
Answer by scott8148(6628)  (Show Source):
You can put this solution on YOUR website! first, find the slope (m) __ the y change (rise) divided by the x change (run)
m=(2-4)/(-3-3) __ m=(-2)/(-6) __ m=1/3
using point-slope __ y-4=(1/3)(x-3) __ distributing __ y-4=(1/3)x-1
adding 4 __ y=(1/3)x+3
