Question 130556
{{{x-y=4}}} Start with the given equation


{{{x=4+y}}} Add y to both sides


{{{x-4=y}}} Subtract 4 from both sides



{{{y=x-4}}} Rearrange the equation




So now the equation is in slope-intercept form {{{y=mx+b}}} where the slope is {{{m=1}}} and the y-intercept is {{{b=-4}}}. Note: the equation really looks like {{{y=1x-4}}}
