Math Problem Statement
What is the slope of the line that passes through the points (-4, 8) and (2, -4)?
Solution
To find the slope of the line, we will use the slope formula:
The two given points on the line are:
Now let's plug these into the slope formula:
So, the slope of the line is .

Here are 5 follow-up questions based on this:
- What does the slope of a line represent in general?
- How would the slope change if the line were horizontal?
- What is the significance of a negative slope?
- Can you identify the y-intercept of this line based on the graph?
- How would you calculate the slope if the points had been flipped?
Tip: The slope represents the rate of change between the two variables (rise over run).
