Question

33 -22
52 -33
71 – 44
What is the x-intercept of the line?

Answer 1

(-5,0)

Explanation:

Answer 2

-5

Explanation:

For each decrease of 11 in y, the x-value increases by 19. So, adding 2·11 = 22 to the first y-value will mean we need to subtract 2·19 = 38 from the first x-value.

The x-intercept will be 33 -38 = -5.
