Responses

(2,81)
left parenthesis 2 comma 81 right parenthesis

(2,82)

(2,15)

Answer 1

To determine which ordered pair is in the solution set for the equation \( y = 8x - 1 \), we can substitute \( x = 2 \) into the equation and compute \( y \).

Calculating:

\[
y = 8(2) - 1
\]
\[
y = 16 - 1
\]
\[
y = 15
\]

So when \( x = 2 \), \( y = 15 \).

Now, we can check the ordered pairs:

- For \( (2, 81) \): \( y \neq 15 \)
- For \( (2, 82) \): \( y \neq 15 \)
- For \( (2, 16) \): \( y \neq 15 \)
- For \( (2, 15) \): \( y = 15 \)

Thus, the ordered pair that is in the solution set for \( y = 8x - 1 \) is \( \boxed{(2, 15)} \).
