4. True or false. If a line L1 has equation y = mx + b, where m and b are constants with m ≠ 0,then an equation of a line L2 perpendicular to L1 has the form y=(-1/m)x+c , where C is a constant.

4.	True or false. If a line L1 has equation y = mx + b, where m and b are constants with m ≠ 0,then an equation of a line L2 perpendicular to L1 has the form   y=(-1/m)x+c  , where C is a constant.

anonymous · Answer

If slope of one is m, then slope of line perpendicular to it is (-1/m), for m not 0. Is rest of statement true?

marziajackson$ · Answer

I would say false

anonymous · Answer

that what I am thinking because a slope of zero would make it a vertical line, right?

marziajackson$ · Answer

Yeah

anonymous · Answer

The question rules out m=0, and the answer is true.

sorry i mean its horizontal

anonymous · Answer

Oh I see what youa re saying douglas, the questions states m not equals zero, so it is true because it cannot be zero!
