Answer
no
Work Step by Step
Substitute the given values and determine whether the resulting equation is true.
$y=3-\frac{x}{5}$
$\frac{1}{10}\overset?=3-\frac{\frac{1}{2}}{5}$
$\frac{1}{10}\overset?=3-\frac{1}{2}\times\frac{1}{5}$
$\frac{1}{10}\overset?=3-\frac{1}{10}$
$\frac{1}{10}\ne2\frac{9}{10}\ \ $
Thus, the ordered pair is not a solution to the equation.
