Hello There!
Well, as you know a number line is a line where you can place numbers with different spaces between them. It can be used to compare them in distance (the further apart they are on the line, the greater the difference between the two numbers)
Hope This Helps You!
Good Luck :)

Answer:
5. A.
6. F
Step-by-step explanation:
5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3
y = 3x + b
using coordinates (-6,3)
3 = 3(-6) + b
b = 21
y = 3x + 21
6. I think F is the right answer
 
        
             
        
        
        
For this you would use Pythagorean theorem (a^2+b^2=c^2) a=15 and c=sqrt 514 plug the numbers in and you’ll be set

Answer: Norm Alpina did better with z-score 0.79
Step-by-step explanation:
Z score formula = (raw score - mean) / standard deviation
For Jack Hartig, 
score = 4; mean = 2.9; standard deviation = 2.1
Hence, Z score = (4 - 2.9) /2.1
= 1.1/2.1
= 0.52
For Norm Alpina,
score = 8; mean = 6.5; standard deviation = 1.9
Hence, Z score = (8 - 6.5) /1.9
= 1.5/1.9
= 0.79
Relatively, Norm Alpina did better for having Z score 0.79
