Question

how do you tell if a functuon is a linear function​

Answer 1

Answer:

if it's y = mx + b or f(x) = mx + b

Step-by-step explanation:

A linear function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept

Answer 2

Answer:

If it's on a graph and it's a straight line then its linear.

If its not on a graph, it will fall under a few different formulas, but as a general rule if it does not have an exponent on the x or y then it'll be linear.
