First we need to solve for y to get it into slope intercept form



3x-y=4 Start with the given equation


-y=4-3x Subtract 3+x from both sides


-y=-3x%2B4 Rearrange the equation


y=%28-3x%2B4%29%2F%28-1%29 Divide both sides by -1


y=%28-3%2F-1%29x%2B%284%29%2F%28-1%29 Break up the fraction


y=3x-4 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=-4
