Question

Explain, in complete sentences, the relationship between the equations of perpendicular lines.

Answer 1

if m is the slope of one line then the slope of the other line is -1/m

Answer 2

I thought it was just their slope is the same.

Answer 3

no - those are parallel lines

Answer 4

Oh.

Answer 5

if we write equations in the slope / intercept form:

y = 3x + 5
y =3x + 7

the slope is 3
and they are parallel
