Answer
slope=-$\frac{4}{3}$
y-intercept=-3
Work Step by Step
When an equation is written in slope-intercept form, it's written as
y=mx+b where m=slope and b=y-intercept
To express the equation 6y=-8x-18 in slope-intercept form, we divide by 6 on both sides to get the equation
y=-$\frac{4}{3}$x-3
Therefore, m=-$\frac{4}{3}$ and b=-3
