Question
The image contains four graphs, each displaying a straight line plotted on a Cartesian coordinate system ranging from -10 to 10 on both the x and y axes. Below is a detailed description of each graph:

1. **Graph 1:**
   - The line passes through the origin (0,0) with a positive slope. It moves upwards from the bottom left towards the top right of the graph.
   - This indicates a direct relationship between the x and y values, where both increase together.

2. **Graph 2:**
   - The line has a negative slope, moving from the top left towards the bottom right of the graph.
   - This suggests an inverse relationship, where y decreases as x increases.

3. **Graph 3:**
   - Similar to Graph 1, this line also has a positive slope and passes through the origin.
   - It reflects a proportional increase between x and y values.

4. **Graph 4:**
   - The line has a positive slope but passes through (0, -10) on the y-axis.
   - This indicates a linear relationship with a y-intercept of -10, shifting the entire line downwards compared to the origin-based lines in Graphs 1 and 3.

These graphs are useful for understanding the basic concepts of linear relationships and the effects of different slopes and intercepts on a line’s position in the coordinate plane.

**Graph the Linear Function Using the Slope and Y-intercept**

Equation given: \( y = \frac{1}{2}x + 5 \)

**Explanation of Graphs:**

The task is to graph the linear equation using the slope (\( \frac{1}{2} \)) and the y-intercept (5).

1. **First Graph:**
   - The line intersects the y-axis at 5, which is correct according to the y-intercept given in the equation.
   - The slope of \( \frac{1}{2} \) is visualized as the line moves up by 1 unit for every 2 units it moves to the right.

2. **Second Graph:**
   - This graph also displays a line through the point (0, 5) on the y-axis.
   - The slope appears consistent with \( \frac{1}{2} \) as it rises by 1 unit for every 2 units moved to the right.

3. **Third Graph:**
   - The line does not align with the correct y-intercept or slope.
   - It intersects the y-axis at a different point and has a negative slope, indicating an incorrect representation of the equation.

The correct graph for the equation \( y = \frac{1}{2}x + 5 \) is the one where the line passes through the y-axis at 5 and follows a slope pattern of rising 1 unit vertically for every 2 units horizontally. The first two graphs align with these criteria.
