Algebra-1

To determine which graph is linear, we need to understand the characteristics of a linear function:

 

1. Straight Line: A linear function will always produce a straight line when graphed on a Cartesian plane.

 

2. Constant Rate of Change: A linear function has a constant rate of change (slope). This means that as x increases by a certain amount, y changes by a consistent amount determined by the slope m.
