Complementary events are the events which are opposite of the given event.
For example, for a "rainy day", its complimentary event is "not a rainy day".
We can also say, If A is a given event, then " not A" is its complimentary event.
In the given question we have been given the event of choosing a girl's name when drawing names from a cup in class.
Now in class as there can be boys or girls, the complimentary even of choosing a girl's name is choosing a boy's name.

Answer:
6/7
Step-by-step explanation:
Given the points :
(-5, 2) and (2, 8)
Slope can be obtained by using the relation :
(y2 - y1) / (x2 - x1)
From the points given :
x1 = - 5 ; y1 = 2 ; x2 = 2 ; y2 = 8
(8 - 2) / (2 - (-5))
(8 - 2) / (2 + 5)
6 / 7
Hence, slope between the two points = 6/7
Last one because it says (6-4)-log:40
