How do you find the intercepts of the equation: x + 2y = 4 To find the xintercept, put 0 in for y: x + 2y = 4 x + 2(0) = 4 {substituted 0 in for y} x = 4 {multiplied 2 by 0} x = 4 {divided both sides by 1} xintercept is 4.......coordinates are (4,0) To find the yintercept, put 0 in for x: x + 2y = 4 (0) + 2y = 4 {substituted 0 in for x} 2y = 4 {simplified} y = 2 {divided both sides by 2} yintercept is 2......coordinates are (0,2) © Algebra House
