Question

this table gives a few (x,y) pairs of a line in the coordinate plane x y -12 14 -2 21 8 8 what is the x intercept of the line?

Answer 1

(-2, 21) and (8, 8)

Explanation:

Use the two coordinate pairs (-2, 21) and (8, 8). As we go horizontally from the first to the second, the run (change in x) is 10 and the rise (change in y) is -13. Thus, the slope of the line through (-2, 21) and (8, 8) is m = rise / run = -13/10.

The equation of this line follows y - k = m(x - h):

y - 8 = (-13/10)(x - 8)

Answer 2

(-32,0)
