Determine whether the lines are parallel, perpendicular, or neither.

y=2x+ 4/3 and y= 3/4 -2x

(4/3 and 3/4 are fractions)

The gradient of a line in the form y = mx + c is "m".

Parallel lines have equal gradients.

Perpendicualr lines have gradients which multiply to give -1.

Anything else is neither. - Nov 7th 2009, 06:20 PMsimpleas123

So they would be neither because they don't.

Thanks for your help!!!
