Answer:
[See Below]
Step-by-step explanation:
You haven't attached any equations so I can't solve this however:
Parallel lines when plotted always have the same gradient.
The general form of line is y = mx + c where "m" is the gradient.
So parallel lines will have "m" to be the same value.
Examples are: y = 6x + 4 and y = 6x - 99
: y = -4x + 2 and y = -4x + 5
