Math Problem Statement

Find the slope, if it is defined, of the line. If the slope is undefined, state this.

Solution

To find the slope of the line, we use the formula:

slope=ΔyΔx=y2y1x2x1\text{slope} = \frac{{\Delta y}}{{\Delta x}} = \frac{{y_2 - y_1}}{{x_2 - x_1}}

From the graph in the first image, we can see that the line passes through two key points:

  1. (4,0)(-4, 0)
  2. (2,3)(2, 3)

Using these points:

  • x1=4x_1 = -4, y1=0y_1 = 0
  • x2=2x_2 = 2, y2=3y_2 = 3

Now, substituting into the slope formula:

slope=302(4)=36=12\text{slope} = \frac{{3 - 0}}{{2 - (-4)}} = \frac{3}{6} = \frac{1}{2}

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

For the question in the second image, the correct answer is:

  • A: The slope is 12\frac{1}{2}.

  3. How would the slope change if the points were vertically aligned?
  4. Can you calculate the slope if only one point is provided?
  5. How does the slope relate to the steepness of a line?

Tip: The greater the absolute value of the slope, the steeper the line.
