Question 1

The graph shows sales in thousands of dollars for 1989 and 1990. Use it to answer the question
 
-If the ordered pair $(x, y)$ represents a point on the graph, what does $x$ represent? What does $y$ represent?
A) $y$ represents the month; $x$ represents the sales in thousands of dollars.
B) $x$ represents the month; $y$ represents the sales in thousands of dollars.
C) $x$ represents the year 2006; y represents the sales in thousands of dollars
D) $x$ represents the year 2006; y represents the year 2007 .

Accepted Answer

In a Cartesian coordinate system, $x$ typically represents the independent variable (such as time, which can include months), and $y$ represents the dependent variable (such as an outcome or result, like sales in thousands of dollars).

Question 2

Question 3

The graph shows sales in thousands of dollars for 1989 and 1990. Use it to answer the question

A) (June, 50)
B) $(6,50)$
C) $(2006,50)$
D) $(50,6)$

Accepted Answer

In an ordered pair $(x, y)$, typically $x$ represents time or a sequence (in this case, the month as a number, with June being the 6th month), and $y$ represents the value or quantity (here, sales, which are approximately 50). Therefore, $(6,50)$ correctly represents the sales in June 2006.
