(1, 2)
x + 3y = 7 2x - 4y = -6
(5, 3)
x - 2y = -1 3y = x + 4
(9, 4)
x - 3y = -3 2x + 5y = 38
the lines are parallel
y = -4x +7 8x +2y = -4 What will this look like when graphed?
(-2, -4)
y = 2x 4x - y = -4
One line (these two equations are the same)
y = 3x -11 3x - y = 11 What will this look like when graphed?
