Question

Write the equation of the line that passes through the points (2,−8) and (1,7). Put your answer in fully reduced point-slope form.

Answer 1

Answer:

y = -15 + 22

Step-by-step explanation:

slope (m):

(y1 - y2)/(x1 - x2)

7 - (-8) / 1 - 2

15 / -1

m = -15

point slope formula:

y - y1 = -15(x - x1)

y - 7 = -15(x - 1)

y - 7 = -15x + 15

y = -15x + 22
