Ms. Aniston asked seven students in her class to collect pet food cans for a local animal shelter. The dot plot shows the number of food cans collected by each student. Each dot represents one student. What is the median of the data set? A. 9 B. 7 C. 6 D. 8

The answer is going to be 7

Step-by-step explanation: So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
