Answer:
you can put anything in the place of -1, but perpendicular to -2/3 is 3/2 so your new equation will be y= 3/2x-1 you can replace -1 with anything you like.
To find the perpendicular of other equations just flip the number so if it was 2/1 it would be 1/2 lets say its negative so, -1/3 it would turn into a positive but your numbers will still flip so it will be 3/1. If it is a positive 5/6 it will turn into -6/5. Hope these example and answer help!

Answer:
- 6.547
Step-by-step explanation:
Given that:
Sample size (n) = 1207
p = 0.85
p0 = 0.92
The test statistic :
Z = (p - p0) / √(p0(1 - p0) / n)
Z = (0.85 - 0.92) / √(0.92(1 - 0.85) / 1207)
Z = - 0.07 / √(0.92(0.15) / 1207)
Z = - 0.07 / √0.0001143
Z = - 0.07 / 0.0106926
Z = - 6.5465446
Z = - 6.547
