Question

Identify all of the linear functions

2x + 5y = 13

-x^3=3y+10

3(2x^4+y)=14

y=13-2x^2

2=y+x^5

y=x+7​

Answer 1

2x + 5y = 13 and y=x+7​

Explanation:

Linear functions are characterized by "first power" for both x and y.

The following equations satisfy that requirement and are thus linear:

2x + 5y = 13

y=x+7​
