Find an equation of a plane through the point (-1, -2, -3) which is orthogonal to the line x=5+2t,y=-3-5t,z=2-2t(adsbygoogle = window.adsbygoogle || []).push({});

in which the coefficient of x is 2.

______________________________=0

i dont get this problem at all, but here's what i came up with after sitting here at the computer for a long time attempting to do this problem.

okay i know that by theorem, The vector a X b is orthogonal to both a and b.

a = <-1,-2,-3>

b= <2,-5,2>

that's all i came up, i attempted many different ways, but it doesnt make sense at all, can someone lend me a hand?
