a)

Step 1:

Draw the scatter diagram from the table

x represents days and y represent set up time

Step 2:

b)

Draw the scatter diagram

Step 3:

c)

Pick two points from the graph to find the linear equation

Points (2 , 16 ) and (6, 11)


\begin{gathered} (y-y_1)/(x-x_1)\text{ = }(y_2-y_1)/(x_2-x_1) \\ \frac{y\text{ - 16}}{x\text{ - 2}}\text{ = }\frac{11\text{ - 16}}{6\text{ - 2}} \\ \frac{\text{y - 16}}{x\text{ - 2}}\text{ = }(-5)/(4) \\ (y-16)/(x-2)\text{ = -1.25} \\ y\text{ - 16 = -1.25x + 2.5} \\ y\text{ = -1}.25x\text{ + 18.5} \end{gathered}

The equation is y = -1.25x + 18.5
