Which of these relations gives a straight-line graph?

Class 8Linear GraphsCoordinate Geometry

A $P = 4 s$
B $y = x \times x$
C $A = s^{2}$
D $V = s^{3}$

Step-by-Step Solution

P = 4 s

increases by the same amount (4) each time

s

goes up by 1, so its graph is a straight line. Squares and cubes give curves.

Answer: A)

P = 4 s
