y = - \frac{4}{3} x - 3

the equation of a line in ' slope intercept form ' is

y = mx + c

where m is the slope and c the y-intercept

here m = - \frac{4}{3} and c = - 3

thus y = -  \frac{4}{3}  x - 3 is the slope- intercept equation

A) The IQR is Q3 - Q1 Q3 is the right edge of the blue box and Q1 is the left edge.

IQR = 25-1 = 24

B) Median values are the line inside the blue boxes:

20-5 = 15

C) the male distribution is asymmetrical and the female distribution is more symmetrical. Because the men are asymmetrical it would be best to describe the distribution using the Median. The women are symmetrical so it would be best to use the mean.

Overall the mean is the most popular/ best way to measure the center.

D) the outlier could be the first day the movie was shown
