Question

Find an equation
of the line through the points of intersection and graph the line
in the same viewing window.

y= x^{2}-4x +3
y= -x^{2} +2x +3

how do I find this line???

Answer 1

find the two points of intersection by solving the two equations simultaneously
using the coordinates of the two points you can find the equation of the line

Answer 2

Im sorry, I need a bit of a refresher. So I use the points (3,0) and (0,3) and plug them into the equations?
