Answer: b 1/x=x/4 +6y
Explanation:
This equation is not linear because it involves a reciprocal term (1/x) and a term containing x multiplied together. Linear equations have terms that involve only constants and variables raised to the first power, and they can be written in the form of "y = mx + b", where m is the slope and b is the y-intercept. The other two equations, (a) and (c), are linear because they can be rearranged into the "y = mx + b" form.
