What is the x -intercept of the line containing the points open paren negative 6 comma 10 close paren and open paren 12 comma negative 2 close paren ?

The slope through the points is (−2 − 10) / (12 − (−6)) = −12/18 = −2/3. Using (−6, 10), the line is y = 6 − (2/3)x; setting y = 0 gives x = 9, so the x-intercept is 9, choice A.
