QuestionFor each line, determine whether the slope is positive, negative, zero, or undefined. \begin{tabular}{|c|c|c|c|} \hline Line 1 & Line 2 & Line 3 & Line 4 \\ \hline & & & \\ \hline Positive Negative Zero Undefined & Positive Negative Zero Undefined & Positive Negative Zero Undefined & Positive Negative Zero Undefined \\ \hline \end{tabular}
Studdy Solution
STEP 1
1. A horizontal line has a slope of zero.
2. A line sloping downward from left to right has a negative slope.
3. A line sloping upward from left to right has a positive slope.
4. A vertical line has an undefined slope.
STEP 2
1. Analyze Line 1.
2. Analyze Line 2.
3. Analyze Line 3.
4. Analyze Line 4.
STEP 3
Analyze Line 1: - Line 1 is a horizontal line. - By assumption, a horizontal line has a slope of zero.
STEP 4
Analyze Line 2: - Line 2 is sloping downward from left to right. - By assumption, a line sloping downward has a negative slope.
STEP 5
Analyze Line 3: - Line 3 is sloping upward from left to right. - By assumption, a line sloping upward has a positive slope.
STEP 6
Analyze Line 4:
- Line 4 is a vertical line.
- By assumption, a vertical line has an undefined slope.
The slopes for each line are as follows:
- **Line 1**: Zero
- **Line 2**: Negative
- **Line 3**: Positive
- **Line 4**: Undefined
