Math Problem Statement
The graph represents the solution set of which of the following equations:
a) 2x - 3y = 0
b) y = (3/2)x - 3
c) y = (2/3)x + 2
d) x = (-2/3)y - 3
Solution
We are given a graph and asked to identify which of the listed equations corresponds to the graphed line.
Let's analyze the graph:
- The line crosses the y-axis at , which suggests the y-intercept is 2.
- The slope of the line appears to be positive since the line rises as it moves from left to right.
- Counting the rise over run, we observe that the slope is .
The equation of a line is generally expressed as , where:
- is the slope.
- is the y-intercept.
From the graph:
- Slope .
- Y-intercept .
Thus, the equation of the line should be , which matches option c).
Conclusion: The correct answer is c) .
