Question

Find the x-intercept of the line 7x+7y= – 1.

Answer 1

(-1/7 ; 0)

Explanation:

the line intercepts the x axis when y = 0

7x + 0 = -1

7x = - 1

7/7 x = -1/7

x = -1/7

Answer 2

The x intercept is -1/7

( -1/7 , 0)

Explanation:

To find the x intercept, set y =0 and solve for x

7x+7y = -1

y =0

7x+7(0) = -1

7x +0 = -1

7x = -1

Divide by 7

7x/7 = -1/7

x = -1/7

The x intercept is -1/7

( -1/7 , 0)
