Cholesterol – The Worst Scenario?

Recall the following task from Unit 5:
Matt’s mom goes to the doctor regularly and has her cholesterol checked. The blood chemistry report shows several measurements related to cholesterol. Matt learned that there is a good kind of cholesterol (HDL) and a bad kind of cholesterol (LDL). In addition to being concerned about the total amount of cholesterol, people have to be concerned about the ratio of total cholesterol to good cholesterol. The average ratio of total to good cholesterol is 4.5 to 1. A ratio above 4.5 to 1 is an increased risk for heart disease. Matt wants you to help him make a graph showing combinations of total cholesterol and good cholesterol readings that would be higher-than-average risks. On the Cartesian coordinate plane, let the x values represent the good cholesterol readings. Graph from 0 to 100 on the x-axis. Let the y values represent the total cholesterol readings, and label the y-axis from 0 to 400.
Matt now wants you to add to the graph you made about cholesterol ratios. He wants a visual representation summarizing the worst-case scenario related to cholesterol. Show on your graph the region that represents increased risk for heart disease based on the ratio of total cholesterol to good cholesterol and increased risk because of the total cholesterol (y>200) and increased risk because of low values of cholesterol (x< 40).
