If a = -12/5, then 5x + 2y = 6 and 3x - ay = 4 are parallel. FALSE.

5x + 2y = 6;

2y = -5x + 6

y = -5/2x +3 the slope of which is -5/2

3x - ay = 4 when a = -12/5,

3x + 12/5y = 4

12/5y = -3x + 4

y = -5/4x + 5/3 the slope of which is -5/4

the slope of the above two lines are not the same so they are not parallel.

5x + 2y = 6;

2y = -5x + 6

y = -5/2x +3 the slope of which is -5/2

3x - ay = 4 when a = -12/5,

3x + 12/5y = 4

12/5y = -3x + 4

y = -5/4x + 5/3 the slope of which is -5/4

the slope of the above two lines are not the same so they are not parallel.
