$y$ $y$ is $46$ $46$ .

Use proportions:

$(\frac{y_{1}}{x_{1}}) = (\frac{y_{2}}{x_{2}})$ $(y_1 / x_1) = (y_2 / x_2)$

$(\frac{166}{83}) = (\frac{y_{2}}{23})$ $(166 / 83) = (y_2 / 23)$

Multiply by $23$ $23$ on both sides:

$(\frac{166}{83}) \cdot 23 = y_{2}$ $(166 / 83) * 23 = y_2$

$46 = y_{2}$ $46 = y_2$

If y=166y=166y=166 when x=83x=83x=83, what is yyy when x=23x=23x=23?
