Final answer:
It is unclear which pair of linear equations is correct without context, but linear equations are typically in the form y = mx + b; examples provided in references show proper linear equation forms.
Step-by-step explanation:
The question as stated appears to involve determining the correct form of a pair of linear equations. Without additional context, it is unclear what the criteria for the 'correct' form are based on. However, typically linear equations are in the form y = mx + b, where m is the slope and b is the y-intercept. Given the information in the provided references about linear equations, we understand that a linear equation should be in the slope-intercept form and both y = 9 + 3x and y = -266.8863 + 0.1656x are examples of linear equations as they follow this pattern with m and b set as specific values.
