Question

Find the x-intercept of the line graphed by the equation 1/2x - 7y = 7.

(0, 14)
(7, 0)
(14, 0)
(0, 7)

Answer 1

(0, 14)

Explanation:

just got it right

Answer 2

(14, 0)

Explanation:

The x-intercept is for y = 0.

Substitute y= 0 to the equation 1/2x - 7y = 7:

1/2x - 7(0) = 7

1/2x - 0 = 7

1/2x = 7 multiply both sides by 2

2 · 1/2x = 2 · 7

1x = 14

x = 14
