If the Celtics win 40% of their games in the first third of their season, what percent of the remaining games would they have to win so they can finish the season with an even record (50%wins)?

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)
