SOLVING SYSTEMS OF EQUATIONS BY GRAPHING
le graphs at the right to determine whether each system has one solution, no
uuon, or infinitely many solutions. If the system has one solution, name it.
y - 2x + 14
y = -x + 5
y = x-3
7 POINTS EACH
y = -x - 4
y = -x + 5
y = 2x + 14
y = -x + 5
y = -x - 4
State whether the given ordered pair is a solution to the system. Circle yes or no. Be
sure to SHOW ALL WORK!
4. YES or NO
x - y = 6
2x + y = 0
(-2,-4)
5. YES or NO
2x - y = 4
3x + y = 1
(1-2)
Solve each system of equations by graphing.
y = 2x + 6
y = -x - 3
