The graphs show different linear equations, and you have three formula options to match with each graph:

1. \( y = 2x \)
2. \( y = \frac{1}{2}x \)
3. \( y = -\frac{1}{2}x \)

Here's how the graphs match with the formulas:

1. Graph 1: This graph has a positive slope that is steeper than graph 2, matching \( y = 2x \).
2. Graph 2: This graph has a gentle positive slope, matching \( y = \frac{1}{2}x \).
3. Graph 3: This graph has a negative slope, matching \( y = -\frac{1}{2}x \).
