Determine the constant of variation for the direct variation given. r varies directly with s. when s is 16, r is 80.

The direct variation says that:

then;

the equation is of the form:

y = kx , where k is the constant of variation.

As per the given statement:

R varies directly with S.

By definition of direct variation:

Substitute the given values S = 16 and R = 80 to solve for k;

Divide both sides by 16 we get;

5 = k

⇒R=5S

Therefore, the constant of variation is, 5
