Final answer:
The linear equations among the given options are: y = 3x + 1 and y = -x + 6.
Step-by-step explanation:
The linear equations are those which can be written in the form of y = mx + b, where m represents the slope and b represents the y-intercept. Based on this definition, the linear equations among the given options are:
- y = 3x + 1
- y = -x + 6
Therefore, options A and B represent linear functions.
