Answer:
A. 1
B.  .
.
Step-by-step explanation:
We have been given an equation of a line  .
.
A. We know that slope of parallel lines is always equal, 
We can see that slope of our given line is 1, therefore the slope of the line parallel to our given line would be 1.
B. We know that the product of slopes of two perpendicular lines is  .
. 
Let m represent slope of perpendicular to our given line, then:


Therefore the slope of the line perpendicular to our given line would be  .
.
 
        
                    
             
        
        
        
I'm pretty sure you can just use a Cartesian plane and since all of your points are (positive, positive) they'd all be in the First Quadrant (top right)
        
             
        
        
        
Answer:False

When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
