Math Problem Statement

Look at the graph provided, how would you identify this slope? What is the slope? How would you show the values in a table?

Solution

Let's analyze the graph and answer the questions based on the "Exit Ticket."

1. How to Identify the Slope

To identify the slope of a line, we calculate the "rise over run." This involves measuring the vertical change (rise) and horizontal change (run) between two points on the line.

In this graph, the points are:

  • (2,2)(2,2)
  • (6,8)(6,8)

2. Calculating the Slope

The formula for the slope mm between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Substitute the values: m=8262=64=32m = \frac{8 - 2}{6 - 2} = \frac{6}{4} = \frac{3}{2} So, the slope of the line is 32\frac{3}{2} or 1.5.

3. Showing the Values in a Table

To represent the values in a table, you can list the x-coordinates and their corresponding y-coordinates:

xy
22
68

You can also include other points along the line that satisfy the equation, which in this case would be: y=32x1y = \frac{3}{2}x - 1

Would you like more details on any of these points or have any questions?

Here are some related questions to consider:

  1. How would you interpret the meaning of a positive slope like 32\frac{3}{2}?
  2. What happens to the line if the slope is changed to a smaller or larger number?
  3. How can you use the equation of a line to predict other points?
  4. What is the y-intercept of this line, and how can it be identified from the equation?
  5. Can you graph this line if given only the slope and a single point?

Tip: The slope tells you the rate of change of yy with respect to xx; a larger slope indicates a steeper incline.
