We can start by doing a substitution using y given by the second equation y=ax+b From the first equation, we can substitute y for ax+b, which gives us x-5(ax+b)=-20 Using distribution, this simplifies to x-5ax-5b=-20 From here, we can find the values of a and be that will give us the equation -20=-20. This would imply infinitely many solutions, since the statement is true regardless of the value of x and y. a=1/5 and b=4 would give us this result: x-5*1/5x - 5*4 = -20 x-x - 20 = -20 -20 = -20

Question- which choice would it be? Top left, top right, bottom left or bottom right?

SmokeyBrown:

Good question! I lost the screenshot, but whichever one has a=1/5 and b=4 would be the one you want
