Cartesian Equations

  1. Jan 26, 2006 #1
    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?
