Find the point of intersection of the two lines.
4x + 4 = 4y y = 2x
4x + 4 = 4y
y = 2x 4x + 4 = 4(2x) {substituted 2x, in for y, into top equation} 4x + 4 = 8x {multiplied 4 by 2x} 12x = 4 {added 4x to each side} x = 1/3 {divided each side by 12} y = 2x {bottom original equation} y = 2(1/3) {substituted 1/3, in for x, into bottom original equation} y = 2/3 {multiplied} x = 1/3 and y = 2/3 {the point of intersection of the two lines} Comments are closed.
