1. Solutions to Systems of Equations

2. Warm Up
Solve the following systems:

3. Solutions to Systems Systems of equations can have:
One solution: one ordered pair satisfies all equations of the system.
Infinitely Many Solutions: the system contains the same equation in different representations:
y=2x+4 is the same as y-2x=4
No solutions: the lines are parallel… meaning they have the same slope:
y=-3x+1 and y=-3x-50 are parallel
