Math Problem Statement

What is the slope of this line?

Solution

To find the slope of the line, we use the formula for slope, which is:

slope=riserun\text{slope} = \frac{\text{rise}}{\text{run}}

Where:

  • Rise is the change in the y-coordinates (vertical change).
  • Run is the change in the x-coordinates (horizontal change).

Looking at the two points on the graph:

  • One point is (2,4)(-2, -4).
  • The other point is (2,2)(2, -2).

Now, calculate the rise (change in yy) and the run (change in xx):

  • Rise: y2y1=2(4)=2+4=2y_2 - y_1 = -2 - (-4) = -2 + 4 = 2
  • Run: x2x1=2(2)=2+2=4x_2 - x_1 = 2 - (-2) = 2 + 2 = 4

So, the slope is:

slope=24=12\text{slope} = \frac{2}{4} = \frac{1}{2}

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

Do you want further clarification or have any additional questions? Here are some related questions you might find useful:

  1. How do you find the slope when given a different set of points?
  2. What happens to the slope if the line is horizontal or vertical?
  3. How do you graph a line using the slope-intercept form?
  4. Can you calculate the slope of a line using just the equation of the line?
  5. What does a negative slope indicate about the direction of the line?

Tip: Always remember that the slope tells you how steep the line is, and its sign (positive or negative) indicates the direction (upwards or downwards).
