Question
Using one coordinate plane, graph the functions y=−4x+1 and y=2x−3, and find the coordinates of the point of intersection. Now find the coordinates of the point of intersection without using the graphs. Compare your two results.

well without graphs
-4x+1=2x-3
-6x = -4
x = 2/3
then
y = 2(2/3) - 6/3
etc
-4x+1=2x-3
-6x = -4
x = 2/3
then
y = 2(2/3) - 6/3
etc

whoops
y = 2(2/3) - 9/3
y = 2(2/3) - 9/3
