Question

Which equation shows a linear relationship between the variables stated?

A. D = 1/2 at2 , for d versus t
B. EK = 1/2 mv2 , for Ek versus v
C. m = f/a, for m versus a
D. V = IR, for v versus i

Answer 1

A and B cannot be the answer because they are square equations and not linear. C also is not the answer because you can't make m/a = something

D is the answer because you can divide both sides by I and get equation
V/I=R. Right side is linear therefore that is the answer.
