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
