To determine which ordered pair is a solution of the equation y = x - 2, substitute the given x and y values into the equation and see if the equation is true.
Checking each option:
a.(3,1):
1 = 3 - 2 is true.
So, (3,1) is a solution.
b.(1,3):
3 = 1 - 2 is false.
So, (1,3) is not a solution.
c.(-1,3):
3 = -1 - 2 is true.
So, (-1,3) is a solution.
d.(3,-1):
-1 = 3 - 2 is false.
So, (3,-1) is not a solution.
Therefore, the solutions are:
a. (3,1)
c. (-1,3)
The correct answer is either (3,1) or (-1,3).
which ordered pair is a solution of the equation y equals x - 2?
a.(3,1)
b.(1,3)
c.(-1,3)
d.(3,-1)
