Question

Which of the following functions have the ordered pair (2, 5) as a solution?

x + 3 = y
7 - x = y
4 + x = y
y = 2 x

Answer 1

y 2x

Explanation:

Answer 2

x + 3 = y and 7 - x = y

Explanation:

Put the value of x = 2 and the value of y = 5 from the given point to the equations and check the equality.

x + 3 = y

2 + 3 = 5

5 = 5 CORRECT

7 - x = y

7 - 2 = 5

5 = 5 CORRECT

4 + x = y

4 + 2 = 5

6 = 5 FALSE

y = 2x

5 = 2(2)

5 = 4 FALSE
