Question 999094
y = 2/3 * x + 2



if x = 0, then y = 2/3 * 0 + 2 = 2
if x = 1, then y = 2/3 * 1 + 2 = 2/3 + 2 = 2/3 + 6/3 = 8/3 = 2 and 2/3
if x = 2, then y = 2/3 * 2 + 2 = 4/3 + 2 = 4/3 + 6/3 = 10/3 = 3 and 1/3
if x = 3, then y = 2/3 * 3 + 2 = 6/3 + 2 = 6/3 + 6/3 = 12/3 = 4


the graph of the equation looks like t his:

when allen's collection is 3 years old, it's value of 400 dollars.


that's because the value of y is in hundreds of dollars.


you could also have graphed this as:


y = 200/3 * x + 200, in which case the value of y would have been in dollars.


the graph of that equation is shown below:

in order to see that, you needed to change the scale of your y-axis from each unit representing 1 to each unit representing 100.
