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!!!
