A graph of the area of a square (y) against its side length (x) is plotted using points (1,1), (2,4), (3,9), (4,16). Is this graph a straight line, and why?

Question

Accepted Answer

No, because area = side^2 grows unevenly. Area = side^2, so increases are 3, 5, 7 (not equal). Unequal steps give a curve, not a straight line.

A graph of the area of a square $(y)$ against its side length $(x)$ is plotted using points (1,1), (2,4), (3,9), (4,16).
