From the slope of the line, we see that 43 is a very steep slope, so the line is a near vertical line.
Also, from the point-slope form of the graph, we know that the line passes through (5,5) .
Note: (y-y1)=m(x-x1) passes through (x1,y1).
So the result is the line shown in the attached diagram, with no surprises.

2(1 to 3) and get 2 to 6
Answer:
a) Percentage of students scored below 300 is 1.79%.
b) Score puts someone in the 90th percentile is 638.
Step-by-step explanation:
Given : Suppose a student's score on a standardize test to be a continuous random variable whose distribution follows the Normal curve.
(a) If the average test score is 510 with a standard deviation of 100 points.
To find : What percentage of students scored below 300 ?
Solution :
Mean 
,
Standard deviation 
Sample mean 
Percentage of students scored below 300 is given by,
Percentage of students scored below 300 is 1.79%.
(b) What score puts someone in the 90th percentile?
90th percentile is such that,
Now, 
Score puts someone in the 90th percentile is 638.
Answer:
542, 543, 544, 545.
Step-by-step explanation:
Divide 2174 by 4 = 543.5
(because there are 4 integers) 543.5 is not an integer.
However, one of the four integers is 543.
Write down four consecutive numbers that include 543 and add them:
like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like
542+543+544+545 = if it's still too low, move up one number again
543+544+545+546=
You only have to do that a max of 3 times to get the answer.
The four consecutive integers are
542, 543, 544, 545.
