So you're graphing it or saying if it's parallel or perpendicular?

Saying if it's parallel or perpendicular

Answer 4

very easy way to do this is to solve both eqns for y, then if the slope is a negative reciprocal then the lines are perpendicular and if slope is the same then the lines are parallel

Answer 5

But wouldn't 12 be neither?

Answer 6

their slopes are not the same and not opposite reciprocals

Answer 7

Riverdale!!

Answer 8

first line has slope of -2

Answer 9

2y = x-3
y = 1/2x - 3/2
1/2 and -2 are opposite reciprocals (for 12)

Answer 10

Thx!

Answer 11

now try 13

Answer 12

Is it parallel?

Answer 13

-3y = x+6
so
y = -1/3x-2
that is the slope for the second one (for 13)

Answer 14

you tell me, if slope is opposite reciprocals is it parallel or perpendicular?

Answer 15

perpendicular

Answer 16

good job : )

Answer 17

thank you!
