У – 5 = 3 – 9(у + 2)
How do I do this?

Y=-1

Step-by-step explanation:

Y-5=3-9y-18

y+9y=3-18+5

10y=-10

y=-1

how am i supposed to answer

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)
