Do you have a possible answer for this one? If so, remember to also show your work you did to arrive at your result.

I'm pretty sure it's D. I graphed it and it passes through (-2,4)

3. LynFran

yes D.. but here how i work it...$-7y=-14x+1$$y=\frac{ -14x }{ -7 }-\frac{ 1 }{ 7 }$$y=2x-\frac{ 1 }{ 7 }$so ur slope=2 and since perpendicular $m _{1}*m _{2}=-1$where $m _{1}=2$now substituting that we get $2m _{2}=-1$$m _{2}=\frac{ -1 }{ 2 }$now using given point (-2,4 )|dw:1442170139078:dw|

Oh ok thanks so much!
