Question

What is the x intercept ?

Answer 1

(3,0)

Explanation:

The x-intercept of the line is where the line crosses the x-axis and the y-value is 0.

This line has a slope of

`m = (y_2-y_1)/(x_2-x_1)= (-48--64)/(-15--21) =(-48+64)/(-15+21) =(16)/(6) =(8)/(3)`

This means that when -32 becomes -32+8=-24 then its x-value is -9+3 = -6.

Continue this pattern until the y value is 0.

-32+8 = -24 and -9+3 = -6

-24+8 = -16 and -6+3 = -3

-16 + 8 = -8 and -3+3=0

-8+8=0 and 0+3 = 3

The x intercept is (3,0).
