The line is 4 units in length.
The z-score of Kimmie is -0.625
<h3>Calculating z-score</h3>
The formula for calculating the z-score is expressed as;
z = x-η/s
where
η is the mean
s is the standard deviation
x is the Kimmie score
Substitute the given parameter
z = 85.9-88.4/4.0
z = -2.5/4.0
z = -0.625
Hence the z-score of Kimmie is -0.625

Answer:
The answer is the option A
The line is horizontal. The slope is 
Step-by-step explanation:
we know that
The slope of the line parallel to the x-axis is equal to zero and is called a horizontal line
The slope of the line parallel to the y-axis is undefined and is called a vertical line
In this problem we have

This is a line parallel to the x-axis
therefore
Is a horizontal line with slope equal to zero
