Question

Describe whether each of the following is linear or not linear. In each case, explain your answer.

A. 3x+4y+2=0

B. X= 2,4,6,8 Y=1,5,15,30

C. You have a secret that you tell to one person. Every hour, each of the people that know the secret tells one person. The number of people who know is N, and t is the number of hours since you told the first person. Is N a linear function of t?

Answer 1

A. This is a linear function because it's standard form of the equation of line; ax + by + c = 0, As well as the fact that is that the variables are to the first power.

Answer 2

B. This is not a linear function there are no equal changes from the x input to the y input from 2 to 4 the change is 4 units from 4 to 6 the change is 10.

Answer 3

C. N is not a linear function of t because N does not change by a constant amount as t changes.

Answer 4

There we go :)
