Anthony spent 1 hours packing boxes into crates. Each box was a cube with sides 4 inches long as shown below, that weighed
between 1.2 pounds and 1.3 pounds.
4 inches

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)
