Question

What is the relationship between the lines determined by these two equations?

3x + 6y = 8
y = 2x – 8

A.
neither parallel nor perpendicular

B.
they are the same line

C.
parallel

D.
perpendicular

Answer 1

A

Answer 2

thanks

Answer 3

D because
y = 2x - 8
&
y = -1/2x + 4/3
Making the slope the opposite reciprocals. AKA. Perpendicular.

Answer 4

oh. So I am going with d

Answer 5

D also

Answer 6

Try installing something called GeoGebra. All you have to do on it is type in those equations and you can see if it is perpendicular, parallel, or neither.

Answer 7

ok

Answer 8

yeah, the way to check for parallel is same slope
perpendicular is opposite reciprocal.
