Question

The ordered pair (3,2) satisfies which of the following equations ?

A. 2x-2y=7

B. 2x-y=5

C. 2x+y=8

D. 2x+2y=6

Answer 1

For the ordered pair (3, 2) to satisfy an equation, the result must be correct when you substitute 3 for x and 2 for y in an equation.

For choice C: 2x + y =8

2*3 + 2 = 6 + 2 = 8

Therefore choice C is the correct equation.

Be sure to check all the choices. In this case, (3,2) is not a valid solution for the equations in choice A, B, or D.
