Math Problem Statement
Solution
The image displays a "Match the Equation to the Graph" activity with linear equations and corresponding graphs. To solve this:
- Analyze the graphs: Identify slopes and y-intercepts for each graph.
- Match equations: Compare with the given equations.
Let’s determine the matches based on the features:
Key features to identify:
- Slope (m): Look at how steep the graph is. Positive slopes go upwards, negative slopes downwards.
- Y-intercept (b): Find where the line crosses the y-axis (x=0).
- Vertical/Horizontal Lines: "x=a" is vertical, and "y=b" is horizontal.
Here’s the process:
Step-by-step Matching:
-
Graph 1: Appears to have a slope of 1/2 and a y-intercept of -3 → Equation: y = (1/2)x - 3.
-
Graph 2: Appears to have a slope of -2 and a y-intercept of -4 → Equation: y = -2x - 4.
-
Graph 3: A horizontal line at y = 3 → Equation: y = 3.
-
Graph 4: A vertical line at x = 3 → Equation: x = 3.
-
Graph 5: Appears to have a slope of -3/2 and a y-intercept of -8 → Equation: y = -(3/2)x - 8.
-
Graph 6: Appears to have a slope of 3/2 and a y-intercept of 8 → Equation: y = (3/2)x + 8.

Relative Questions:
- What is the difference between positive and negative slopes?
- How can you identify a vertical line equation?
- Why does the y-intercept occur at ?
- How do you calculate the slope from a graph?
- What happens to the graph when only the slope changes?
Tip:
Always start with the y-intercept to narrow down the equation possibilities quickly.
