Question

The table below represents a function.

x
1
2
3
4
5
y
6
12
18
24
30

Which statement would best describe the graph of the function?
The graph is a straight line that has a slope of 6.
The graph is a horizontal line at y = 6.
The graph starts flat but curves steeply upward.
The graph is a parabola that opens upward.

Answer 1

The graph is a straight line that has a slope of 6.

Reason: As x increases by 1, y increases by 6 (6, 12, 18, ...), so the data lie on the line y = 6x with slope 6.
