Please show a picture of the diagram.
Sale price = original price - discount
discount = 44% of original price = 44% of $37 = 0.44 x 37 = $16.28
Sale price = $37 - $16.28 = $20.72
Tan 2 pi/3= (sin2pi/3)/(cos2pi/3)= (sqrt 3)/2 dividend by (-1/2)= - sqrt 3
For this case we must find the slope of the following equation:

By definition, the point-slope equation of a line is given by:

Where:
: It is a point through which the line passes
m: It's the slope
So, the slope of the given equation is:

Answer:
Option D
