#### Answer

slope = $-\frac{2}{3}$
y-intercept = $2$

#### Work Step by Step

RECALL:
The slope-intercept form of a line's equation is $y=mx+b$ where $m$ = slope, $b$= y-intercept.
Write the given equation in slope-intercept form by isolating $y$ on one side:
$3y=-2x+6
\\y =\dfrac{-2x+6}{3}
\\y=-\frac{2}{3}x + 2$
Thus, the slope of the line is $-\frac{2}{3}$ and the y-intercept is $2$.
