Question

which of the lines, if any, are parallel

Answer 1

Answer:

a and c are parallel.

Step-by-step explanation:

Let's find slope for each line.

If slopes of lines are same then they are parallel.

for line described by a : slope = $\frac{0-(-2)}{1-(-1)}$ = 1

For line b slope = $\frac{-2-2}{2-4}$ = 2

For line c slope = $\frac{1-2}{-1-0}$ =1

So slope of lines a and c are same. a and c are parallel to each other.
