Question

Which equation represents the line that passes through (-6, 7) and (-3, 6)?

y=-*x+9
y=-*x+5
y=-3x – 1ly
y=-3x + 25

Answer 1

y = -3x - 11

Explanation:

(y - y1)/(x - x1) = (x2 - x1)/(y2 - y1)

(y - 7)/(x + 6) = (-3 + 6)/(6 - 7)

(y - 7)/(x + 6) = 3/-1 = -3

y - 7 = -3(x + 6)

y - 7 = -3x - 18

y = -3x -18 - 7

y = -3x - 11
