Question

For each pair of lines, determine whether they are parallel, perpendicular, or neither

Line1 : 2y=5x+7
Line2: 4x+10y=8
Line3: y=5/2x-4

Answer 1

Answer: Lines 1 &3 are parallel with each other and line 2 is neither

Explanation:

After singling out y for lines 1 & 2 you see they have the same slope 5/2 x

But for the second line it intersects worth both lines but does not make a 90 degree angle
