To find the slope,we can use the slope formula:
Where x and y are y coordinates and x coordinates respectively.
To find the answer, put any two points into the formula.
In this case, (1,5) and (0,-1) will be used:
x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)
Therefore the answer is 6.

Answer:
Mean value is 0 and standard deviation is 1 after all test scores have been standardized by converting them to z-scores using z
Step-by-step explanation:
In a standard normal distribution (also called as <em>Gaussian distribution</em>) all values of the sample can be projected to a normal distribution with mean 0 and standard deviation 1 using their z-scores.
z-score of a value X can be calculated as follows:
z= where
- 50 is the <em>mean of the test scores</em>
- 6 is the <em>standard deviation of test scores</em>
