Do you want to solve for y?




3x-y=6 Start with the given equation


-y=6-3x Subtract 3+x from both sides


-y=-3x%2B6 Rearrange the equation


y=%28-3x%2B6%29%2F%28-1%29 Divide both sides by -1


y=%28-3%2F-1%29x%2B%286%29%2F%28-1%29 Break up the fraction


y=3x-6 Reduce



So the equation is now in slope-intercept form (y=mx%2Bb) where the slope is m=3 and the y-intercept is b=-6
