Answer:
line L is not parallel to AB
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 4 - 2x ( divide terms by 3 )
y =
-
x ← in slope- intercept form
with slope m = - 
Calculate slope of AB using the slope formula
m = 
with (x₁, y₁ ) = A(1, 3) and (x₂, y₂ ) = B(- 2, - 1)
=
=
= 
Parallel lines have equal slopes
Since the slopes are not equal then the lines are not parallel
