Math Problem Statement
Find the slope, if it is defined, of the line. If the slope is undefined, state this.
Solution
To find the slope of the line, we use the formula:
From the graph in the first image, we can see that the line passes through two key points:
Using these points:
- ,
- ,
Now, substituting into the slope formula:
Thus, the slope of the line is .
For the question in the second image, the correct answer is:
- A: The slope is .
