Question

Which of the following equations represents a line that passes through the points (6,-16) and (-3,2)

Answer 1

y=-2x-4

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-(-16))/(-3-6)

m=(2+16)/-9

m=18/-9

m=-2

y-y1=m(x-x1)

y-(-16)=-2(x-6)

y+16=-2(x-6)

y=-2x+12-16

y=-2x-4

Answer 2

Neither

Explanation:

y2 - y1 -16 - 2 -18

---------- = ----------- = -------- = 2

x2 - x1 -3 - 6 -9

y = mx + b

-16 = 2(6) + b

-16 = 12 + b

-12 -12

-28 = b

y = 2x - 28

y = mx + b

2 = 2(-3) + b

2 = -6 + b

+6 +6

8 = b

y = 2x + 8

I hope this helps!
