Question

Which equation represents the line passing through the points (3,2) and (-9,6)?​

Answer 1

Equation of line: y = mx + b

m = slope

m = y2 - y1 / x2 - x1

m = 6 - 2 / -9 - 3

m = 4/-12

m = -1/3

Plug in One of The Points to Solve for b:

(3,2)

y = -1/3(x) + b

2 = -1/3(3) + b

2 = -1 + b

b = 3

Answer:

y = -1/3(x) + 3
