Math Problem Statement
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. Calculating the Slope
The formula for the slope between two points and is: Substitute the values: So, the slope of the line is 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:
x | y |
---|---|
2 | 2 |
6 | 8 |
You can also include other points along the line that satisfy the equation, which in this case would be:
Would you like more details on any of these points or have any questions?
Here are some related questions to consider:
- How would you interpret the meaning of a positive slope like ?
- What happens to the line if the slope is changed to a smaller or larger number?
- How can you use the equation of a line to predict other points?
- What is the y-intercept of this line, and how can it be identified from the equation?
- Can you graph this line if given only the slope and a single point?
Tip: The slope tells you the rate of change of with respect to ; a larger slope indicates a steeper incline.
