Question

Which of the following equations describe the line shown below? Check all that apply. (6,1) (12,3)

A. Y-3=3(x-12)
B. Y-12=3(x-3)
C.y-1=1/3(x-6)
D.y-6=1/3(x-1)
E.y-3=1/3(x-12)
F.y-1=3(x-6)

Answer 1

`The\ point-slope\ formula:y-y_1=a(x-x_1)\\-----------------------\\\\for\ (6;\ 1)\to y-1=a(x-6)\\\\for\ (12;\ 3)\to y-3=a(x-12)\\\\Answer:\boxed{A.;\ C.;\ E.;\ F.}`
