Question

What do the following equations represent -4x-4y=-5 and x-2y=1

A=equal lines
B=parallel lines
C=perpendicular lines
D=none of the above

Answer 1

The answer to your question is: D = non of the above

Explanation:

Data

-4x - 4y = -5 (I)

x - 2y = 1 (II)

Process

Find the slopes of both lines

(I) -4x - 4y = -5

-4y = 4x + 5

y = 4/-4 x + 5/-4

y = - x + 5/4

(II) x - 2y = 1

- 2y = - x + 1

y = -1/-2 x + 1/-2

y = 1/2 x - 1/2

The slopes are different slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
