Question

Select linear or nonlinear to correctly classify each function

Answer 1

Answer:

1. Non - linear

2. Linear

3. Linear

4. Linear

Step-by-step explanation:

All linear equations can be expressed in the form of  

$y=mx+b$

where m is slope and b is y-intercept.

Horizontal line is a special case of linear functions, where slope is 0. It means y=b is also a linear funcion.

First function is

$72=x^3+y\Rightarrow y=-x^3+72\neq mx+b$

It is a non linear function.

Second function is

$y+1=5(x-9)\Rightarrow y=5x-45-1\Rightarrow y=5x-46=mx+b$

It is a linear function.

Third function is

$7y+2x=12\Rightarrow y=\dfrac{12-2x}{7}=-\dfrac{2}{7}x+\dfrac{12}{7}=mx+b$

It is a linear function.

Fourth function is

$4y=24\Rightarrow y=6=0x+6=mx+b$

It is a linear function.
