    Question vector equation for line perpendicular to cartesion equation through point

    Could someone help me with this please.

    Question asks "Find a vector equation for the line perpendicular to 3x-4y+10=0 and passing through the point (1,-2)".

    I really don't know how to start this off.

    There are many approaches. A simple one is to start by getting the cartesian of the line. Then express this equation in parametric form (which is not unique, by the way). Then use the parametric equations to write the vector equation.
