y = x represents a straight POSITIVE line that goes through the origin (0, 0) and stretches from the 3rd quadrant all the way through the 1st quadrant

y = - 2x + 3

y-intercept: (0, 3)       Slope, or m = - 2

1) Start at the y-intercept, (0, 3)

2) Go up 2 units, then go LEFT, 1 unit

3) Go DOWN 2 units, the go RIGHT 1 unit

4) Join the points

5) Find the coordinates of the INTERSECTION of the 2 graphs.

You're done!! Nothing too complex!
