Question 784792
y=mx+b

5y=-4x-5 Divide both sides by 5
y=(-4/5)x-1

5y=2x+2  Divide both sides by 5
y=(2/5)x+(2/5)

5y+4x=-1 Subtract 4x from both sides
5y=-4x-1 Divides both sides by 5
y=(-4/5)x-1

Parallel lines have the same slope. (m) equals slope so y=mx+b. So 1 and 2 are parallel because both of their slopes are (-4/5)
