Determine whether each pair of lines is parallel, perpendicular or neither.

6. the line containing points x(8, -3) and y(-4, -6).

the line containing points r(1, 4) and s(-3, -3).

7. the line containing points a(2, -1) and b(3,-4).

the line containing points c(1,6) and d(3, 0).

8. y= 2x + 1
2y = -x-1

9. 4x - y = 2
8x - 2y = -6

i dont know sorry

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
