Q:

What do the following equations represent -4x-4y=-5 and x-2y=1A=equal lines B=parallel lines C=perpendicular lines D=none of the above

Accepted Solution

A:
Answer:The answer to your question is: D = non of the aboveStep-by-step explanation:Data           -4x - 4y = -5        (I)              x - 2y = 1          (II)ProcessFind 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 - 1/2The slopes are different   slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
