Question

consider the line 6x-4y=-6
What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

Answer 1

perpendicular: y=-2/3x-6

Answer 2

-4y=-6x-6
y=3/2+3/2

parallel= 3/2

perpendicular= -2/3

Answer 3

parallel: y=3/2x-(any number)

Answer 4

ax +by = c ->

by = c -ax

y = c/b -ax/b so

slope is -a/b
