1.
-3x - 4y = -3
-4y = 3x -3
y = (-3/4)x + 3/4
2.
y = -3/4x + 3/4 &
y = -1/2x + 2
are NOT parallel because the gradients are different. The gradients are the coefficients of 'x' and as '-3/4' is not equal to '-1/2' the lines are not paraallel.

-4y = 3x - 3
y = -3/4x - 3/4
2. the slope of this is -3/4 and the Part 2 slope is -1/2 so it is not parallel.

-3x - 4y= -3
-3x+3 =4y
y= -3x/4 +3/4
slope of this line = -3/4
slope of y = -1/2x + 2 is -1/2
Parallel lines have same slope so these 2 lines cant b parallel.

-4y=3x-3
y=-3/4 x - 3
It is not parallel. Parallel lines have the same slope, ie, in the y=mx+b form the m is the slope

y = -(3/4)x + 3/4
Lines are parallel if they have the same slope so these two lines are not parallel.
