When a line passes through the two points 
, its slope is given by the formula 
In this question, a line L passes through the points 
So, its slope is given by 
When two lines are perpendicular, then the product of their slopes is -1.
Since, the slope of the line L is 
, so the slope of the line which is perpendicular to the given line L is 
as the product of 
.
we are given with the set of data containing the elements listed above and is asked to find out the standard deviation of the data. SD is used to determine the distance between the points to the best fit line gained from the data. The formula to be followed is the square root of the summation of (x-mean) over n-1. sd is equal to <span>5.13.</span>

Answer: 0.28
Step-by-step explanation:
Answer:
The last graph
Step-by-step explanation:
This is because when there is a greater than sign, the line on the graph is dotted and the shaded area is facing upwards. I try to remember that when there is a greater than sign or a greater than or equal to sign, the shaded area faces up towards the sky.
Hope this helps. Please inform me if my answer is wrong.
