Total points in a board game based on the average number of hours played is predicted using the least-square regression line, 9 = 280.3 + 85.7%, where ý represents the total points scored and x represents the average number of hours spent playing the game. A player plays the game for an average of 3 hours and has a point total of 550. What is the residual for the player? (3
points)
03.15
O-12.6
0 -3.15
12.6

probably the last option

step-by-step explanation:

where is the option given

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
