Math Problem Statement

What is the slope of the line?

Solution

The graph shows a straight line, and the question asks for the slope of the line.

To calculate the slope, we can use the formula:

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

Looking at the points where the line crosses grid intersections, we can identify two points:

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

Now, using these points in the slope formula:

slope (m)=244(4)=68=34\text{slope (m)} = \frac{-2 - 4}{4 - (-4)} = \frac{-6}{8} = -\frac{3}{4}

So, the slope of the line is:

m=34m = -\frac{3}{4}

Here are 5 related questions to explore:

  1. How does the slope of a line change if the line becomes steeper?
  2. What is the significance of a negative slope versus a positive slope?
  3. How can we determine the y-intercept of the line from the graph?
  4. What is the equation of the line in slope-intercept form?
  5. How would the graph change if the slope were 0?

Tip: Always check two clear points on a graph when calculating the slope to avoid errors.
