You can put this solution on YOUR website! find the coordinates to graph -x - y = -8 and -3x + 4y =2
we should use the formula y = mx + b where m is slope (y/x) and b is y intercept
1) -x -y = -8
-y = x - 8
y = -x + 8 and x = 8 - y
here are two points (0,8) and (8, 0)
2) -3x + 4y =2
4y = 3x+2
y = (3/4)x + 1/2 and x = (4/3)y - (2/3)
here are two points (0, 1/2) and (-(2/3), 0)
