For which functions is this statement true?
A) y = 2(3)x
B) y = 2(9)x
C) y = 3x + 2
D) y = 9x + 2

im not sure what the answer is

step-by-step explanation:

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)
