I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:
-- You pick two points on the graph line.
-- Find the difference in 'y' between the two points.
-- Find the difference in 'x' between the two points.
-- The slope of the line between the two points is
(the difference in 'y')
divided by
(the difference in 'x') .
-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.
Answer:
Step-by-step explanation:
Given that Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard deviation of 6 inches.
If X is height then X is N(55,6)
Z score would be 

b) 
c) Tallest 10% z = 1.28
X score =
inches
d)
i.e. 16.37% cannot go on this ride.
