#### Answer

$\color{blue}{y=-\frac{5}{4}}$

#### Work Step by Step

RECALL:
(1) The point-slope form of a line's equation is $y-y_1=m(x-x_1)$ where $m$=slope and $(x_1, y_1)$ is a point on the line.
(2) The slope-intercept form of a line's equation is $y=mx+b$ where $m$=slope and $(0, b)$ is the line's y-intercept.
The given line has a slope of $0$ and a y-intercept of $(0, -\frac{5}{4})$.
Substitute these into the slope-intercept form in (2) above to obtain:
$y=0x-\frac{5}{4}
\\\color{blue}{y=-\frac{5}{4}}$
This equation cannot be written in slope-intercept form.
