Homework Help: Parametric line intersecting with x and y axis

  1. Sep 4, 2008 #1
    Consider the line L(t)=<4t-1,2+2t>. Then L intersects:
    1. the x-axis at point ____ when t=____
    2. the y-axis at point ____ when t=____
    3. the parabola y=x^2 at the points _____ and _____ when t=_____ and t=______

    I am confused on how to approach this problem. Do I just make x=4t-1 and y=2+2t?
