$m = \frac{9}{2}$ $m=9/2$
Y Intercept $= \frac{1}{2}$ $= 1/2$

Explanation:

The given equation is in the general form $a x + b y + c = 0$ $ax+by+c = 0$
Solve it to slope intercept form
$- 2 y = - 1 - 9 x$ $-2y = -1-9x$
$y = \frac{- 1}{- 2} - \frac{9}{- 2} x$ $y=(-1)/(-2)-9/(-2)x$
$y = \frac{1}{2} + \frac{9}{2} x$ $y=(1)/(2)+9/2x$

The co-efficient of $x$ $x$ is slope of the curve $m = \frac{9}{2}$ $m=9/2$
The constant term $(\frac{1}{2})$ $(1/2)$ is Y-intercept
