Answer

(2, 15) isn't a solution.

(4, 9) is a solution.

Step-by-step explanation

We are asked to examine each of the ordered pairs given and determine if they are a solution of y = 4x - 7

If the ordered pair is a solution, it will sastisfy the given expression.

Note that ordered pair is written in the form (x, y)

For the first one

(2, 15)

x = 2, y = 15

y = 4x - 7

15 = (4 × 2) - 7

15 = 8 - 7

15 ≠ 1

So, this ordered pair isn't a solution.

For the second one

(4, 9)

x = 4, y = 9

y = 4x - 7

9 = (4 × 4) - 7

9 = 16 - 7

9 = 9

Hence, this ordered pair is a solution.

Hope this Helps!!!
