Math Problem Statement

What is the slope of this line?

Solution

To determine the slope of a line given two points, we use the formula:

slope=m=y2y1x2x1\text{slope} = m = \frac{y_2 - y_1}{x_2 - x_1}

From the graph, the two points provided are:

  • Point 1: (3,2)(-3, -2)
  • Point 2: (6,4)(6, 4)

Plugging these into the slope formula:

  1. Calculate the difference in yy-values: y2y1=4(2)=4+2=6y_2 - y_1 = 4 - (-2) = 4 + 2 = 6

  2. Calculate the difference in xx-values: x2x1=6(3)=6+3=9x_2 - x_1 = 6 - (-3) = 6 + 3 = 9

  3. Substitute these values into the slope formula: m=69=23m = \frac{6}{9} = \frac{2}{3}

So, the slope of the line is 23\frac{2}{3}.

Here are five related questions that expand on this topic:

  1. How do you find the slope of a line if given the equation instead of points?
  2. What does a positive or negative slope indicate about the direction of a line?
  3. How can you find the equation of a line given a point and the slope?
  4. How do you find the slope of a line parallel to a given line?
  5. What is the slope of a vertical or horizontal line?

Tip: Remember that the slope represents the "rise over run" between two points on a line, showing the line's steepness.
