The mean absolute deviation of the boys' basketball team at Washington High School for the past six games is 6.8 when rounded to the nearest tenth. Here are the steps for the solution of the problem. The mean of the following scores is 75.33. Get the absolute value of the difference of each value and the mean then divide it with 6.

Part 1)

Part 2)

Part 3)

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-intercept

Part 1) we have

(10,-3) (5,-2)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

Find the value of b

we have

substitute in the equation  and solve for b

substitute

Part 2) we have

(6,2) (7,5)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

Find the value of b

we have

substitute in the equation  and solve for b

substitute

Part 3) we have

(4,4) (-7,4)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

This is a horizontal line (parallel to the x-axis)

The y-intercept b is equal to the y-coordinate

therefore

The equation of the line is
