Checking and Ordered
Pair
Ch 8.2
Goal: Input an ordered pair
into an equation to see if it is a
solution
Substitute the Ordered pair (-3, 1) into each
equation and solve algebraically.
x+y=-2
-3 + 1 = - 2
-2 = - 2 √
Yes, it is a
solution
2x + 3y = -9
2(-3) + 3(1) = -9
-6 + 3 = - 9
-3 = - 9 NO
No, it is not a
solution
Stay organized and keep writing the next
step underneath until you get to the end.
Your Turn

Determine if the ordered pair is a solution to the
linear equation
1.
3x – 2y = 11; (5, 2)
2.
2x + y = -3; (-2,1)
3.
x + 3y = 15; (3, -6)
4.
-5x + y = 19; (-4, -1)
