In 2004, there were about 73.9 million pet dogs in the U. S. In 2017, there were about 89.7 million pet dogs in the U. S. Write a linear equation to represent the number of pet dogs d, in millions, t years after 2000. Round to the nearest hundredth. Please help I'm not smart at all

dont think so

step-by-step explanation:

b

step-by-step explanation:

this is because the profit is decreasing and turning into debt

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)
