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

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

Step-by-step 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.

i got 86 for this

hope this !

if you need an explanation just ask

just sum

10 + 10 = 20
