SUMMARY
The discussion revolves around calculating the slope of a line using the points (-2, -1) and (3, 2). The initial claim that the slope is 4:2=2 is incorrect. The correct method to find the slope involves using the formula for slope, which is defined as rise over run. Participants emphasize the importance of clarity in visual representations, as the original image was difficult to interpret.
PREREQUISITES- Understanding of coordinate geometry
- Familiarity with the slope formula (rise/run)
- Ability to interpret graphical data
- Basic algebra skills
- Study the slope formula in detail, including examples
- Practice calculating slope using various pairs of points
- Learn how to create clear graphs for better visual representation
- Explore common mistakes in slope calculations and how to avoid them
Students learning algebra, educators teaching coordinate geometry, and anyone seeking to improve their skills in calculating slopes and interpreting graphs.

Are you asking about problem 5? If so, your answer is wrong. For the two points you marked, what is the rise (vertical change) and what is the run (horizontal run)?Rabinow23 said:
I get a slope that is less than 1.
In the future, if you post an image, please make more of an effort to post a legible picture. The image you posted was photographed at and angle, and there is a crease in the paper, making it somewhat hard to read.

I said I got a number less than 1.Rabinow23 said:
From your graph, it appears that the points you're using are (-2, -1) and (3, 2). You have labeled this points, but the image is too poor for me to read them -- I just counted squares on the grid.
If you know two points on a line, how do you find the slope of that line?

No. Are you just guessing?Rabinow23 said:
Do you know the formula for calculating the slope of the line between two points?
In your first post in this thread you wrote:
That is not the formula for the slope of a line.Rabinow23 said:

Rabinow: Slope is given by rise/run. Can you figure it out?
