Can anyone help me with this please I’ll give u brainliest

I think the answer is B please tell me if I am wrong.

Step-by-step explanation:

just sum

10 + 10 = 20

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)
