hi! : )

a farmer that lived in ancient egypt would most likely be barried in the sand, in the desert!

d is ur answer hopes this i dont really know how to explain it to u.

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)
