There are 20 people who work in a office together. five of these people are selected to go to a conference. how many selections are possible?
a. 100
b. 2400
c. 15,504
d. 1,860,480

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

b and c are the correct answers.

good luck on the quiz! : d
