Question

State the slope of a line that is perpendicular to the line by each given function.
y=-5x-3
y=x
x=-3

Answer 1

How do you find that?

Answer 2

first find the slope (it's the m in y = m x + b form)

Answer 3

the perpendicular slope is -1/m when the slope is m

Answer 4

so for the first one it is 1/5
the second it is -1
the third it is y=0 (or y = any constant) ... this one is a special case

Answer 5

... the special case is that for an undefined slope (x=constant) the perpendicular is zero slope (y=constant)
