Answer:
Sorry please accept i need points for an answer
Step-by-step explanation:
12) Linear function.
13) Linear function.
14) Non-linear function.
Step-by-step explanation:
First we define Linear and non-linear functions.
The Equation of linear function has no exponent having degree greater than 1, and the graph of linear function is a straight line
The Equation of non-linear function has exponent having degree greater than 1, and the graph of linear function is a curved line.
12) 2x+3y=7
This equation satisfies the definition of linear function, so it is linear function.
13) y+x=4x+5
This equation satisfies the definition of linear function, so it is linear function.
14) 
This equation satisfies the definition of non-linear function, so it is non-linear function.
