#### Answer

$-4$;
$3$

#### Work Step by Step

RECALL:
The equation $y=mx+b$, where m = slope and b = y-intercept, is called the slope-intercept form of a line's equation.
The given equation has $m=-4$ and $b=3$.
Thus, the given line has a slope of $-4$ and a y-intercept of $3$.
Therefore, the missing expressions in the given statement are:
$-4$;
$3$
