SOLUTION
Graph Y
= -5, Y
= 3x - 2, and Y
1
2
Xscl = 1, Ymin = -8, Ymax = 4, Yscl = 1. We wish to find the point of intersection
between Y
and Y
and the point of intersection between Y
1
2
the point of intersection between Y
the CALC menu and select 5:
INTERSECT. When First Curve?
appears, the cursor should be on Y
Move the cursor near the point of
intersection and press ENTER.
After pressing ENTER, the cursor automatically jumps to Y
near the point of intersection.
Press ENTER a third time and you obtain the point of intersection as (-1, -5).
We now wish to find the point of intersection between Y
menu and select 5: INTERSECT. The first curve is on Y
accomplished by pressing the down arrow. Move the cursor near the point of intersection
and press ENTER. The cursor jumps to Y
intersection and press ENTER. Press ENTER a third time to obtain your solution, (1, 1).
= 1 using the viewing window Xmin = -8, Xmax = 8,

and Y
. After graphing all three equations, bring up

We know we are TRACEing
on Y
.

. Again, move the cursor near the point of
3
and Y
. We will first find

because of this!!
