I'm sorry I only am good at math :L

OpenStudy (solomonzelman):

Yes, you are correct!

OpenStudy (solomonzelman):

\(\color{black}{\displaystyle y-y_1=m(x-x_1) }\), and when \(\color{black}{\displaystyle (x_1,y_1) =(-2,9) }\) you get \(\color{black}{\displaystyle y-9=m(x+2) }\).

OpenStudy (solomonzelman):

oh, I left out to plug in the slope for some reason:( And m=-1/4 ...

OpenStudy (solomonzelman):

So, yes, your answer is correct.

OpenStudy (iluvsoccer):

Thanks! :) Quick question though, why does it turn to addition? :/

OpenStudy (solomonzelman):

\(\color{black}{\displaystyle x-(-2)=x+2 }\)

OpenStudy (solomonzelman):

Double negative is positive.

OpenStudy (iluvsoccer):

Ooookay. Thanks again! :)
