Question

What is the slope of a line that is perpendicular to the line whose equation is ax+by=c?

A) a/b B) b/a C) -b/a D) c/b

Answer 1

condition of two line is perpendicular is multiplication of their slopes is=-1.

Answer 2

perpendicular to the slope
so two slopes must be the negative reciprocal of each other

an example would be
3/4 and -4/3

or
-2 = 1/2

Answer 3

So, A?

Answer 4

are you know the slope of given line?

Answer 5

I don't know whether it's A or B

Answer 6

ax+by=c
in slope-intercept form it will be
y = (-ax+c)/b

we the have -a/b so its negative reciprocal
- (b/-a) = b/a
