Use graphing technology (TI calculator or Desmos) to find the linear regression equation that models the data. Let x equal the hours of sleep and y equal test score. Explain the steps you use. Use the equation to determine the approximate test score of a student who sleeps an average of 7.5 hours a night. Show your work.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
