Final answer:
Unable to determine the correct equation for the number of steps Alya takes based on minutes walked without additional information such as steps per minute.
Step-by-step explanation:
The question is asking to find the equation that represents the number of steps, y, Alya will take if she walks for x minutes. To solve this, we need additional information such as the walking speed or average steps per minute. As no additional information is provided, and given that this is a practice scenario, we cannot determine the specific relationship between the time walked (x) and the number of steps (y). Each of the provided options (A, B, C, D) are linear equations, which fit into the general linear equation format y = mx + b, where m is the slope and b is the y-intercept. Without specific details, such as average steps per minute, we cannot accurately choose between these equations.
