Do you know how to find the vertex of a parabola? |dw:1401995282925:dw|
|dw:1401995393173:dw| If we can figure out the x-coordinate of that vertex then we can figure out the equation of that line drawn here through the parabola at that particular point.
Can you figure out the x-coordinate of the vertex?
