Answer
$x$;
$y$;
$\frac{1}{2}$
Work Step by Step
The y-intercept can be found by setting $x=0$ in the given equation then solving for $y$.
Thus, the y-intercept of $2y=x+1$ is:
$2y=0+1
\\2y=1
\\y=\frac{1}{2}
\\-1=x$
Therefore, the missing expressions in the given statements (in order) are:
$x$;
$y$;
$\frac{1}{2}$
