What is a box plot? how does it work? ?

mark brainliest :))

Step-by-step explanation:

In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range. the median is marked by a vertical line inside the box. the whiskers are the two lines outside the box that extend to the highest and lowest observations.

- (2, -7)

- lines r and s and lines t and u must be parallel
