**Helper**, Tuesday, February 22, 2011 at 8:00pmSolve without graphing first so that you know what x and y equal.

Then pick three points for each to graph.

3x + y = 6

x = 1, y = 3

x = 2, y = 0

x = 3, y = -3

2x + 3y = 13

x = 1, y = 11/3 = 3.67 (3.67 is a little more than 3 1/2)

x = 2, y = 3

x = 3, y = 7/3 = 2.34 (2.34 is a little more than 2 1/4).

Since you have already solved without graphing, and know the solution for x and y, this should help to see where the lines should intersect.

The solution for this system is,

x = 5/7 = 0.71 approx. which is about 3/4

y = 27/7 = 3 6/7 approx. which is about

4)

Good luck :)
