Question 125964


{{{x-y=12}}} Start with the given equation



{{{-y=12-x}}}  Subtract {{{ x}}} from both sides



{{{-y=-x+12}}} Rearrange the equation



{{{y=(-x+12)/(-1)}}} Divide both sides by {{{-1}}}



{{{y=(-1/-1)x+(12)/(-1)}}} Break up the fraction



{{{y=x-12}}} Reduce




So the equation is now in slope-intercept form ({{{y=mx+b}}}) where the slope is {{{m=1}}} and the y-intercept is {{{b=-12}}}
