y = x + 6
y = -2x - 3
(-3,3)
y = 4x - 1
y = 2x - 5

Slope
y = x - 1
x + 4y = 16
(4,3)
y = 6x
2x + 3y = -20
(-1,-6)
3x - 10y = 14
3x - 9y = 15
(8, 1)

1
y = 2/3x - 1
y = -x + 4
(3,1)
x = 4y + 7
2x - 6y = 12
(3,-1)
4x + 9y = 5
-4x + 7y = 11
(-1,1)

Suppose we have parallel lines, how many solutions we got?
5x + 4y = -12
3x - 4y = -20
(-4,2)
2x + y = -2
5x + 3y = -8
(2,-6)
3x - 4y = -10
3x - 4y = -13
No solution
Someone is going to lose points.......
Yeah you........let us roll a dice!
If we have 2 equations and we graph them and they end up being the same exact line, how many solutions do we have?
Infinite!
2x + y = 8
x = 5
(5,-2)
3x - y= -8
5x + 2y = 5
(-1, 5)
x = 3y + 11
2x - 3y = 16
(5,-2)
