How do you find the x and y intercepts of: x  8y + 7 = 0? To find the xintercept, put 0 in for y: x  8y + 7 = 0 x  8(0) + 7 = 0 {substituted 0 in for y}
x + 7 = 0 {multiplied 8 by 0} x = 7 {subtracted 7 from both sides} xintercept is 7 To find the yintercept, put 0 in for x: x  8y + 7 = 0 0  8y + 7 = 0 {substituted 0 in for x} 7 = 8y {added 8y to both sides} y = 7/8 {divided both sides by 8} yintercept is 7/8  Algebra House
