MATH302 B012 Win 20 Tests & Quizzes Tests & Quizzes Week 7 Knowledge Check Homework Practice Questions Return to Assessment List Part 1 of 9 - Linear Regression and Correlation 2.0/ 2.0 Points Question 1 of 20 Due to erosion, a river shoreline is losing several thousand pounds of soil each year. A linear equation that expresses the total amount of soil lost per year is y = 12,000x. How many pounds of soil does the shoreline lose in a year? Answer: 12000 1.0/ 1.0 Points Answer Key: 12000 Feedback: The slope is 12,000. The change in the slope impacts the linear equation. Since the slope is 12,000 and this is the change in the line, the shoreline will lose 12,000 pounds of soil each year. Question 2 of 20 Which of the following equations are linear? • A. 4y=8 • B. y2=6x3+8 • C. 3y=6x+5y2 • D. y-x=8x2
