Math Problem Statement

What is the slope of the line?

Solution

To find the slope mm of the line shown in the graph, we can use the formula:

m=ΔyΔx=y2y1x2x1m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}

Where:

  • (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are two points on the line.

Let's identify two points on the line from the graph:

  1. Point 1: (4,0)(-4, 0)
  2. Point 2: (0,2)(0, 2)

Using these points:

m=200(4)=24=12m = \frac{2 - 0}{0 - (-4)} = \frac{2}{4} = \frac{1}{2}

So, the slope mm of the line is 12\frac{1}{2}.

Tip: When working with slopes, remember that a positive slope means the line rises as it moves from left to right, while a negative slope means the line falls.
