PLZ HELP ME 50 POINTS

indicate whether the lines are parallel, perpendicular, or neither (for all of them this is NOT multiple choice

1)y=3/2x - 3 and -2x = 3y - 4

2)x+4y = -12 and 24y= -6x - 72

3)4x - 14y = -112 and 14x + 4y =16

Answer 1

1) perpendicular
2) parallel
3)perpendicular

Answer 2

1) Because they have opposite reciprocal slopes it is perpendicular
2) They have the same slope so they are parallel
3) They have opposite reciprocal slopes so they are perpendicular
