Step by Step Solution
Step 1
Looking at the reference picture below, the line on the right has a positive slope.
Therefore, the slope for this line is correctly labeled.
Therefore, the slope for this line is correctly labeled.
Step 2
Looking at the reference picture below, the line on the right has a negative slope.
Therefore, the slope for this line is correctly labeled.
Therefore, the slope for this line is correctly labeled.
Step 3
Next, looking at the reference picture below, the line on the right has zero slope.
Therefore, the slope for this line is should be zero and not infinite.
Therefore, the slope for this line is should be zero and not infinite.
Step 4
Looking at the reference picture below, the line on the right has infinite slope.
Therefore, the slope for this line is should be infinite and not zero.
Therefore, the slope for this line is should be infinite and not zero.
Step 5
Finally, looking at the reference picture below, the line on the right has negative slope.
Therefore, the slope for this line is should be negative and not positive.
Therefore, the slope for this line is should be negative and not positive.
Step 6
Of all the 5 lines, only 2 are correctly labeled. Hence, the answer is B.
