I forgot what's the formula again.

OpenStudy (alexandervonhumboldt2):

y-y_1=m*(x-x_1)

OpenStudy (alexandervonhumboldt2):

m is slope (x1, y1) is the point

Elsa213 (elsa213):

What do you think the correct answer is?

jabez177 (jabez177):

A?

OpenStudy (alexandervonhumboldt2):

no not A

OpenStudy (alexandervonhumboldt2):

first of all slope if -2/3, not 2/3

OpenStudy (alexandervonhumboldt2):

and you got wrong in the sign of x coodinate

jabez177 (jabez177):

Ohhh! D.

OpenStudy (alexandervonhumboldt2):

it is not D as well lol

Elsa213 (elsa213):

C :D

jabez177 (jabez177):

Okay, I'm now 100% sure it's C. I'm not guessing.

Elsa213 (elsa213):

cx

jabez177 (jabez177):

Oh, fail. Lag.

OpenStudy (alexandervonhumboldt2):

why? i would chose B

Elsa213 (elsa213):

xD

OpenStudy (alexandervonhumboldt2):

xause formula is y-y1=m*(x-x1) not x+x1

jabez177 (jabez177):

Because you said it's negative so I thought Subtraction and you said the x is on the wrong area so I thought C.

OpenStudy (alexandervonhumboldt2):

lol
