Is 2x+3y=5 a linear function? explain

Yes it is a linear function.

Yes, this equation is a linear function. Here are a couple of reasons:

1. The two variables have a degree of 1. Simply put, their exponents are 1's. An exponent greater than one on either or both variables (like x², y³, etc.) will be nonlinear.

2. This equation can be solved for y and be written in the linear form y=mx+b:

2x+3y=5

3y = - 2x + 5

y = - 2/3x + 5/3
