Tricia and Chandra love to go to restaurants, but want to save money by eating at home. The double line graph below shows how many meals they ate at restaurants per week for a 7-week time period. Trisha is blue. Chandra is Red.  What was Tricia’s rate of meals at restaurants per week for the given seven-weeks (i.e. compute a unit rate from the given data). Round to two decimals as needed.  I just wanted to confirm my understanding due to all I could find was regular graphs with increasing constant lines. My question is how should I find a unit rate on a graph like this. Thank you
