(Type an integer or decimal rounded to two decimal places as needed.)
B. The slope is undefined.
Studdy Solution
STEP 1
1. We are given two points: and .
2. We need to find the slope of the line that passes through these points.
3. The slope will help determine if the line is increasing, decreasing, horizontal, or vertical.
STEP 2
1. Recall the formula for the slope of a line given two points.
2. Substitute the given points into the slope formula.
3. Calculate the slope.
4. Determine the nature of the line based on the slope.
STEP 3
Recall the formula for the slope of a line given two points and :
STEP 4
Substitute the given points and into the slope formula:
Let and .
STEP 5
Calculate the slope:
STEP 6
Determine the nature of the line based on the slope:
Since the slope is negative, the line is decreasing.
The correct choice is:
A. The slope is .
