Find the equations that have the given properties. Write your answers in slope-intercept form. Here is the point-slope formula: y-y = m(x-x) Show your work in the space provided below. 1. Find the equation of the line that has a slope of -4 and passes through the point (-3, 7). 2. Find the equation of the line that passes through the points (4, -3) and (8, 9). Linear Regression Use the following table to answer the following questions. x 0 1 4 5 6 6 7 8 9 10 y 1 3 7 6 8 9 9 10 11 12 3. Create a scatterplot using the data in the table above. Note: You can draw the scatterplot using the Word tools, or you can draw the scatterplot by hand, then photograph or scan your graph to submit it. 12 10 8 6 4 2 0 2 IN 3 8 9 10 12 10 8 6 4 2 0 4. After creating the scatterplot: Divide the data into three regions. Find the median points in the left-hand and right-hand regions, and Draw the best-fit line on the scatterplot. Note: You can use the Word tools to graph the data required, or you can draw the graph by hand, then photograph or scan your graph to submit it. 2 3 The median point in the left-hand region is: The median point in the right-hand region is: SS 9 10 5. Find the equation of the best-fit line that models the data. Write the equation in slope- intercept form. Show your work in the space provided below. 6. Using the equation of the best-fit line, predict the y-value when x = 11. Is this an extrapolation or an interpolation? 7. Using the equation of the best-fit line, predict the y-value when x = 2. Is this an extrapolation or an interpolation?
