Determine if each function is linear or nonlinear.



Drag each function into a box to correctly classify it.



y = 2x^3

y = x + 5

y = x^2 -3

5x + 5y = 25

y = x^2/2

Answer 1

Equation B, D are linear. Rest are not.
The first one is cubic. The third and fifth are quadratic.

Answer 2

ANSWER

The linear functions are,

`y = x + 5`
and


`5x + 5y = 25`

Step-by-step explanation

All linear functions can be written in the form

`y = mx + c`

or


`ay + bx + c = 0.`

From the given options the two functions that are of these forms are


`y = x + 5`

and


`5x + 5y = 25`

The remaining ones are non linear because their highest degree is not 1.

Moreover, their graphs are not straight lines, meanwhile the graph of all linear functions are straight lines.
