Question 2
Graph the table of (x, y) coordinates. Does the table represent two quantities that are proportional to each other?
Responses
A No, the plotted points lie on a line that passes through the origin.No, the plotted points lie on a line that passes through the origin.
B Yes, the plotted points lie on a line that passes through the origin.Yes, the plotted points lie on a line that passes through the origin.
C No, the plotted points lie on a line that does not pass through the origin.No, the plotted points lie on a line that does not pass through the origin.
D Yes, the plotted points lie on a line that does not pass through the origin.

Answer 1

The value that completes the table is 12.

The table represents two quantities that are proportional to each other because the plotted points lie on a line that passes through the origin. Therefore, the correct response is B. Yes, the plotted points lie on a line that passes through the origin.
