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

Write a recursive sequence that represents the sequence defined by the following explicit formula:

Answer asap ! the shortest path from point a to point b goes through a pond. to avoid the pond, you must walk straight 34 meters along one edge of the pond, then take a 90 degree turn, and again walk straight 41 meters along another edge of the pond to reach point b. about how many meters would be saved if it were possible to walk through the pond? a. 11 m b. 20 m c. 30.45 m d. 21.73 m
