Answer:
-[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
For linear equations that have been written in the form
y = mx + b,
m represents the slope
hence by comparing this equation to what you have in your question,
slope = m = -[tex]\frac{2}{3}[/tex]
All lines that are parallel to this line will have the same slope of m = -[tex]\frac{2}{3}[/tex]
