Math Problem Statement

Find the slope of the line graphed below.

Solution

To find the slope of the line, we need to identify two points on the line and then use the slope formula:

slope=y2y1x2x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}

Looking at the graph, we can clearly see two points where the line crosses the grid:

  1. (3,2)(-3, 2)
  2. (2,4)(2, -4)

Now, applying the formula for the slope:

slope=422(3)=65\text{slope} = \frac{-4 - 2}{2 - (-3)} = \frac{-6}{5}

Thus, the slope of the line is 65-\frac{6}{5}.

Tip:

When reading a graph, always look for clear grid points where the line passes through to avoid estimation errors in determining the slope.
