Checkpoint: Variation Solutions

Fill in the blanks.

For the equation $y = \frac{2}{3 x},$ y varies inversely as x, and the constant of variation is $\frac{2}{3} .$

Write the equation symbolically.

$y = k \sqrt{x}$

Note

Q: What does the variable k represent?

A: The constant of variation

Q: How can you write problem B) with an exponent instead of a square root symbol?

A: $y = k x^{\frac{1}{2}}$
