You can put this solution on YOUR website!
y=mx%2Bb is slope intercept form (memorize formula)
m=-1%2F5
x=-3
y=0
.
plug into formula to find (b)
0=%28-1%2F5%29%28-3%29%2Bb
0=3%2F5%2Bb
-3%2F5=b
.
write out equation without y and x numbers
y=%28-1%2F5%29x-3%2F5
now get x and y on one side
highlight%28%281%2F5%29x%2By=-3%2F5%29
according to above formula u gave me
A=1%2F5
B=1
C=-3%2F5
