Math Problem Statement

What is the slope of this line?

What is the slope of the line?

Solution

To find the slope of the line shown in the graph, we can use the formula for the slope, which is:

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

From the graph, we can identify two points on the line:

  • Point 1: (4,3)(-4, 3)
  • Point 2: (4,3)(4, -3)

Now, let's apply the slope formula:

m=334(4)=64+4=68=34m = \frac{-3 - 3}{4 - (-4)} = \frac{-6}{4 + 4} = \frac{-6}{8} = -\frac{3}{4}

Thus, the slope of the line is 34-\frac{3}{4}.

Here are 5 related questions for further understanding:

  1. How does the sign of the slope affect the direction of a line?
  2. What is the meaning of a zero slope?
  3. How can you find the slope from the equation of a line?
  4. What does the slope of a vertical line look like?
  5. How do you convert the slope into an angle with respect to the x-axis?

Tip: A negative slope indicates that the line is decreasing, or going downwards from left to right.
