Math Problem Statement

Does the following graph represent the linear equation -2x - 5y = 10?

Solution

To determine whether the given graph represents the linear equation 2x5y=10-2x - 5y = 10, we need to check if the equation corresponds to the line plotted.

Step 1: Convert the equation to slope-intercept form.

The equation is given as: 2x5y=10-2x - 5y = 10

Solve for yy: 5y=2x10-5y = 2x - 10 y=25x+2y = -\frac{2}{5}x + 2

Thus, the slope of the line is 25-\frac{2}{5}, and the y-intercept is 22.

Step 2: Analyze the graph.

  1. The y-intercept (yy-value where x=0x = 0) should be 22. Check whether the graph passes through the point (0,2)(0, 2).
  2. The slope indicates that for every increase of 55 units in xx, yy decreases by 22. This translates to points such as (0,2)(0, 2), (5,0)(5, 0), and so on.

Step 3: Verify the points.

From the graph:

  • Check if the line passes through (0,2)(0, 2).
  • Check if the line passes through another point consistent with the slope (e.g., (5,0)(5, 0)).

  1. The line appears to pass through the y-intercept at (0,2)(0, 2), which is consistent with the equation y=25x+2y = -\frac{2}{5}x + 2.
  2. The slope of the line seems to match 25-\frac{2}{5}, as for every 5 units increase in xx, yy decreases by 2 units (e.g., the points (0,2)(0, 2) and (5,0)(5, 0)).

Conclusion:

The graph does represent the linear equation 2x5y=10-2x - 5y = 10. The correct answer is True.
