Math Problem Statement
The slope and y-intercept of a line based on a given graph.
Solution
The image shows a graph with a line crossing through a grid, along with two questions:
- The slope of the line (select):
- The y-intercept of the graph (select):
Let me analyze the graph to determine the slope and y-intercept.
- Y-intercept: The y-intercept is the point where the line crosses the y-axis.
- Slope: The slope can be calculated by finding two points on the line and using the formula:
Let me extract this information.From the graph, we can make the following observations:
- Y-intercept: The line crosses the y-axis at .
- Slope: We can observe two points on the line, for example, at and .
To find the slope, we use the formula:
Thus:
- The slope of the line is .
- The y-intercept is .
