Of the three lines 4x+6y=-2, 3y=2x+5 and y=3/2x+5. Determine whether th

Question

is this equation parallel, perpendicular, or neither

Answer 1

1st line:  m₁ = -4/6 = -2/3

2nd line:  m₂ = 2/3

3rd line:  m₃ = 3/2

 

Note that 

 

m₃ = -1/m₁ ⇒ 1st line is perpendicular to 3rd line

 

The other pairs of lines are "neither".
