How do you find the x and y intercepts of: x - 8y + 7 = 0?

To find the x-intercept, 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}

x-intercept is -7

To find the y-intercept, 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}

y-intercept is 7/8
