We are given a table starting with year 1992 and going until year 2000. It says these are the closing prices for NASDAQ Stock Index at the end of February. There are three columns in the table - the year, x, and the price. By the year 1992, the first year, the x is 0.

Question

We are given a table starting with year 1992 and going until year 2000. It says these are the closing prices for NASDAQ Stock Index at the end of February. There are three columns in the table - the year, x, and the price. By the year 1992, the first year, the x is 0.

So the y-intercept would be (0, 633) - (633 is the price shown for 1992)

1. What does the y-intercept represent?
I said it represents the closing stock index price in 1992

2. Would an x-intercept make sense in this case? If so, find it. If not, explain why.
I think no, but I'm not sure??????

Answer 1

I agree with #1

#2, the x-intercept would represent a time prior to 1992.
Assuming that the graph is a straight line, you would have a NASDAQ Stock Index of zero, which would not be reasonable
