Use the image to answer the question.

A graph shows both the x-axis and y-axis, ranging from negative 10 to 10 in increments of 5. A line passes through the first, second, and third quadrants.

Answer 1

To determine which ordered pair is part of the solution set for the equation \( y = 2x + 5 \), you can substitute the x-coordinate from each ordered pair into the equation and see if the resulting y-coordinate matches.

1. For the pair \( (3, -1) \): \[ y = 2(3) + 5 = 6 + 5 = 11 \quad (\text{not } -1) \]

2. For the pair \( (1, 7) \): \[ y = 2(1) + 5 = 2 + 5 = 7 \quad (\text{matches }) \]

3. For the pair \( (1, 2) \): \[ y = 2(1) + 5 = 2 + 5 = 7 \quad (\text{not } 2) \]

4. For the pair \( (7, 1) \): \[ y = 2(7) + 5 = 14 + 5 = 19 \quad (\text{not } 1) \]

The only ordered pair that satisfies the equation \( y = 2x + 5 \) is \( (1, 7) \).

So the answer is \( (1, 7) \).
