Choose whether the lines given below are parallel, perpendicular or neither. 4x  6y = 9; 3x  2y = 11
6y+4x=9 2y+3x=11
6y=(9/6)(4/6x) 2y=(11/2)(3/2)
y=2/3x+3/2 y=3/2x+11/2
so they would be perpendicular.
Is this right??

Reiny,
slope of 4x6y=9 is 2/3
slope of 3x2y = 11 is 3/2
so neither parallel nor perpendicular
for the equation
Ax + By + C = 0
the slope is  A/B

Ariel,
Thank you:)

Ellie,
Decide whether the pair of lines is parallel, perpendicular or neither: 2x+3y=3 2x+3y=10
