You can put this solution on YOUR website!

given:
a graph with the ordered pair (3,3)=(x,y), and
the y-intercept -5=> means you are given b=-5 or a point (0,-5)
now, we use slope-intercept form to figure out my equation and slope m:
y=mx%2Bb...substitute -5 for b, 3 for x, and 3 for y
3=m%2A3-5.....solve for m
3%2B5=3m
8=3m
highlight%28m=8%2F3%29
so, your equation is: y=%288%2F3%29x-5

and here is a graph:
