Answer:
Reflection across the x-axis: (-4,2) 
Reflection across the y-axis: (4,-2)
Step-by-step explanation:
Going based off of what I see, a reflection across the x axis changes "y" & the same rule applies to the y axis.
It should be an L shape.
 
        
             
        
        
        
Answer:
Constant of proportionality(X:Y) = 1:6 
Step-by-step explanation:
Given:
 X- 5, 6, 7, 8, 9 
Y- 30, 36, 42, 48, 54
Find:
Constant of proportionality
Computation:
X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54
X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6
So;
Constant of proportionality(X:Y) = 1:6 
 
        
             
        
        
        
Answer:
Substitute the numbers below x by x in the equation given in the middle of the table and that will be the answer for y.
Step-by-step explanation:
 For example, x= -1
y= x + 6
y= -1 + 6
y= 5
 
        
             
        
        
        
Answer:
(0.0757;0.1403)
Step-by-step explanation:
1) Data given and notation
Republicans =115
Democrats=331
Independents=54
Total= n= 115+331+54=500

Confidence=0.98=98%
2) Formula to use
The population proportion have the following distribution

The confidence interval for the population proportion is given by this formula

We have the proportion of independents calculated

We can calculate 
And we can find  , with this value we can find the critical value
, with this value we can find the critical value  using the normal distribution table, excel or a calculator.
 using the normal distribution table, excel or a calculator.
On this case 
3) Calculating the interval
And now we can calculate the interval:


So the 98% confidence interval for this case would be:
(0.0757;0.1403)
