question in the picture line from x = 40 to x = 300.5.28 Measuring water quality. Biochemical oxygen demand (BOD) measures organicpollutants in water by measuring the amount of oxygen consumed by microorganismsthat break down these compounds. BOD is hard to measure accurately. Total organiccarbon (TOC) is easy to measure, so it is common to measure TOC and use regres-sion to predict BOD. A typical regression equation for water entering a municipaltreatment plant is ¹1BOD = -55.43 +1.507 TOCBoth BOD and TOC are measured in milligrams per liter of water.(a) What does the slope of this line say about the relationship between BOD andTOC?(b) What is the predicted BOD when TOC = 0? Values of BOD less than 0 areimpossible. Why do you think the prediction gives an impossible value?

Given: Regression equation is: BOD=-55.43+1.507(TOC) where BOD=biochemical oxygen demand TOC=total…
