If  the equation of a line is 2x + 3y = 6, what is the slope of the line?

The given equation of the line is $2x + 3y = 6$.

Step 1: Solve for $y$ in terms of $x$:
$3y = -2x + 6$
$y = -\frac{2}{3}x + 2$

Step 2: Identify the slope:
From the equation $y = -\frac{2}{3}x + 2$, the slope of the line is $-\frac{2}{3}$.

Answer: The slope is $-\frac{2}{3}$.
