Segment AB falls on line 6x + 3y = 9. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD? They are parallel because they have the same slope of −2.
They are perpendicular because they have slopes that are opposite reciprocals of −2 and one half.
They are parallel because they have the same slope of 2.
They are perpendicular because they have opposite reciprocal slopes 2 and negative one half.

parallel, both slopes are -2

Step-by-step explanation:

AB:  3y = -6x + 9;   y = -2x+3

CD:  2y = -4x + 8;  y = -2x+4

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
