You can put this solution on YOUR website!
y = %281%2F3%29x+%2B+2
set equal to 0
0+=+%281%2F3%29x+%2B+2
subtract 2 from both sides to isolate x
-2+=+%281%2F3%29x
multiply both sides by 3
-2%283%29+=+3%281%2F3%29x
highlight_green%28x+=+-6%29
...
y = -(x)-9
set equal to 0
0 = -(x)-9
add 9 to both sides
9 = -x
divide both sides by -1
highlight_green%28x+=+-9%29
...
y = (.25)x
set equal to 0
0 = (.25)x
divide both sides by .25
highlight_green%28x=0%29
...
y = -(x-5)
distribute the negative
y = -x + 5
set equl to 0
0 = -x + 5
subtract 5 from both sides
-5 = -x
divide both sides by -1
highlight_green%28x+=+5%29
