Question

19. Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

y=-7/8x-1
32x - 28y=-36 (1 point)
A.parallel
B.perpendicular
C.neither

Answer 1

Are the slopes the same? If so they are parallel
Are the slopes negative reciprocals of one another? If so they are perpendicular
No to both of those questions? Then they are neither

Answer 2

@alquana, get them both in the form y =mx +b. See for yourself!

Answer 3

ok i did but i'm just checking to see if i be having the correct answer!

Answer 4

What is your answer?

Answer 5

neither

Answer 6

Did you solve for y with this equation? 32x - 28y=-36

Answer 7

The slope of the first one is 7/8
The slope of the second one is -8/7
-8/7 is the negative reciprocal of 7/8 so therefore they are??????

Answer 8

Whoops. I got the signs backwards. The slope of the first one is -7/8
The slope of the second one is 8/7
The conclusion is the same.

Answer 9

It's okay. So the first slope is -7/8 and 8/7

Hey Alquana, go onto google and graph:

y= -7x/8
and:
y=8x/7

See what they both look like.

Answer 10

ok
