Hello,
I have a quick question... I was doing a question on ellipses in an example and it says that
All lines perpendicular to 6x+2y+3=0 are of form 2x-6y=k....
I don't get why this is and when I rearrange it I absolutely fudge it. Could someone please tell me a quick way to work this out without having to go through the whole rearranging process that I somehow always screw up?
Thanks
EDIT: The whole question I am referring to:
Determine the equations of the tangents to the ellipse x2+16y2=25 which are perpendicular to the line 6x+2y+3=0, and find their points of contact with the curve
