Main Question or Discussion Point

Find the Cartesian equation of each of the following lines.

(x,y)=(4,-6) + t(8,2)

Not sure how to do it, I know that you need the normal which is (-2,8)

I've tried alot of times and I don't get it

You just have to eliminate the parameter t or you can just use the information you can immediately derive from this equation (i.e. its slope and a point it goes through) to set-up the cartesian equation.

Shouldn't this be posted in the help section?
