D=none of the above

Answer 1

they are perpendicular lines

Answer 2

The answer to your question is: B = parallel lines

Explanation:

Data

4x - 2y = - 5 (I)

16x - 8y = -2 (II)

Find the slopes of both lines

(I) 4x - 2y = -5

- 2y = - 4x - 5

y = -4/-2 x - 5/-2

y = 2x + 5/2 slope = 2

(II) 16x - 8y = -2

- 8y = -16x - 2

y = -16/-8 x - 2/-8

y = 2x + 1/4 slope = 2

As the slopes are the same, they are parallel lines.
