Answer:
Equation of line , 5x + 3y = 0
Step-by-step explanation:
The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by 
Here points are given by (-3,0) and (-6,5)
Slope
The slope of parallel lines are same. So slope of required line 
Equation of a line with slope m passing through origin is given by
y =mx
So equation of line, 
Equation of line , 5x + 3y = 0
