Part 1
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A.
The slope is [ ]. (Simplify your answer.)
B.
The slope is undefined.
To find the slope of the graph, we can use the formula:
slope = (change in y)/(change in x)
Let's look at the changes in the y-values and x-values from the given table:
Change in y: 1 - (-5) = 1 + 5 = 6
Change in x: 1 - (-2) = 1 + 2 = 3
So, the slope is 6/3 = 2.
Therefore, the correct choice is:
A. The slope is 2.
