I see two lines that are gonna cross at some point. how did you get your answer ?

anonymous · Answer

Found the slope, plugged it into slope form, did the same for the other line then found the slope for the other line not good at explaining my work, if you didn't get that.

anonymous · Answer

Almost positive I'm missing something though.

math&ing001 · Answer

No i get it, must be a small error in calculus. I just draw the lines |dw:1459958945792:dw|

math&ing001 · Answer

Following your method:
m1=(y2-y1)/(x2-x1)=-1/2
m2=(y2-y1)/(x2-x1)=1
The slopes are different so it can't be A or D.
