Which two lines are parallel?


I. 5y=-3x-5



II.5y=-1-3x



III.5y-2x=-1



a.

I. and II.

c.

II. and III.

b.

I. and III.

d.

No two of the lines are parallel.

Verified Answer :

Equation: 5y=-3x-5
Divide Equation by 5, 
y = -3/5 - 1

Slope = -3/5

Equation: 5y=-1-3x
Divide Equation by 5, 
y = -3/5x - 1/5

Slope = -3/5

Equation: 5y-2x=-1
5y = 2x - 1
Divide equation by 5, 
y = 2/5 x - 1/5

Slope = 2/5

We know, Parallel lines must be same slope, & 1st and 2nd has same so they are parallel.

In short, Your Answer would be Option A) I and II

Hope this helps!
