Question 945287
Solving for y, we get



{{{2x-2y=8}}}



{{{2(x-y)=8}}}



{{{2(x-y)/2=8/2}}}



{{{x-y=4}}}



{{{x-y+y=4+y}}}



{{{x=4+y}}}



{{{x-4=4+y-4}}}



{{{x-4=y}}}



{{{y=x-4}}}



Graph of {{{y=x-4}}}



{{{ graph( 500, 500, -10, 10, -10, 10, 0,x-4) }}}



Slope is 1. Y-intercept is -4
