Where
μ is the average
is the standard deviation
x is the data to which we will calculate the z-score
In this case
So
A z-score is unusual if 
or 
Finally
and this Z-score is “unusual.”
(4, ?) is on 8x - 3y = -10
The ? is the missing y coordinate. (4, y) satisfies 8x - 3y = -10
8x - 3y = -10. From point (4, y), we would replace x = 4 in the equation below. y remains the unknown.
8*4 - 3y = -10
32 - 3y = -10
-3y = -10 - 32
-3y = - 42
y = -42/-3
y = 14
So the coordinate is (4, 14)
