Answer:
sample response: Use the values in the table to create ordered pairs. Label the x-axis with the independent variable, hours. Label the y-axis with the dependent variable, dollars. Plot the ordered pairs on the graph. If the variables can be represented as fractional parts you can draw a line from the origin that connects the points.
12, 15, 15, 18, 20, 29, 33, 42
18 and 20 are in the middle, add and divide to find the answer.
18 + 20 = 38
38 / 2 = 19
19 is the median.
I think it is D, because the negative would turn positive and move to the right but im not 100% sure
