Given:
You scored 12, 8, 15, and 21 points during your first four basketball games.
To find"
The mean score per game.
Solution:
We have,
Observations =12, 8, 15, and 21 points
Number of observations = 4
We know that,
The mean score per game is
Therefore, the mean score per game is 14 points.

Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:
When x = 0 then: So we plot the value (0,-3) on the x-y plane.
When x = 2 then: So we plot the value (2,-2) on the x-y plane.
When x = 0 then: So we plot the value (4,-1) on the x-y plane.
Please see the points and the resulting line in the image attached
