Answer:
The slope of a line parallel to the given line is m = -3/2.
Explanation:
Here, the given equation is

The given equation is of the form y = mx + C : where m is the slope and C is y-intercept.
Here, comparing m = (-3/2) and C = 0
So, slope of the given equation is m = -(3/2)
Also, two equations are said to be parallel if they have equal slopes.
⇒Slope of the line parallel to the given equation: m = (-3/2)
Hence, the slope of a line parallel to the given line is m = -3/2.
