Math Problem Statement

Find the slope of the line graphed below.

Solution

To find the slope of the line graphed in the image, we need to use two clear points on the line. From the graph, it appears there are two distinct points: approximately (3,1)(-3, 1) and (2,4)(2, 4).

The slope mm of a line passing through two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is given by the formula:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Using the points (3,1)(-3, 1) and (2,4)(2, 4):

m=412(3)=35m = \frac{4 - 1}{2 - (-3)} = \frac{3}{5}

Thus, the slope of the line is 35\frac{3}{5}.

Would you like a more detailed breakdown of the calculation or have any questions about this problem?

Here are some related questions to expand your understanding:

  1. How do you determine the slope if the line is vertical?
  2. What would the slope be if the line were horizontal?
  3. How can you interpret a negative slope visually on a graph?
  4. What does a slope of zero imply about the line’s direction?
  5. How does the slope affect the steepness of a line?

Tip: Remember, a positive slope indicates the line rises as it moves from left to right, while a negative slope means it falls.
