Question

Y=x+3 is it a linear function?

Answer 1

Explanation:

A linear function has a variable raised to the power of 1 in it. It takes on the form y = mx + b, where m is the slope and b is the y-intercept. Because our function has x raised to a power of 1, then yes, this is linear (unlike something like 1/x or x²)

Answer 2

It is a linear function because it is of the form:

y=mx+C,

in this case: m=1 and C=3.
