Questions:
Solve each system of equations by graphing.
1)
{7=3x+4
{2y=6x-2
2)
{-3y=9x+1
{6y= -18x -2
3)
{4x - y = -5
{-8x + 2y = 15
Please tell me if i am right or way off.
My answers:
1)
4=y-3x
2)
1=-3y-9x

You did them wrong, sorry. When you graph, the two lines will cross at a point. That ordered pair will be the 'answer' to the system.
