Final answer:
Equations A and B are linear because they can be written in the form y = mx + b. Equations C and D are not linear because they involve x raised to a power other than 1.
Step-by-step explanation:
The linear equations are equations of the form y = mx + b, where m and b are constants. In this case, equations A and B are linear because they can be written in the form y = mx + b.
A: y = -3x
B: y = 0.2 + 0.74x
Equations C and D are not linear because they have terms involving x raised to a power other than 1.
C: y = -9.4 - 2x
D: y = 3,000(x) + 500
