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 $2$.
