For a certain type of injury, the equation yˆ=4.094x+6.255 models the number of minutes a patient can walk on a treadmill, where x is the number of sessions they had since their recovery began.

What does the y-intercept of the equation represent in context of the situation?


Before beginning recovery, patients can walk about 6 min on a treadmill.
Patients are expected to complete 4 training sessions.
Before beginning recovery, patients can walk about 4 min on a treadmill.
Patients are expected to complete 6 training sessions.

We are given a model regarding the number of minutes a patient can walk on a treadmill in the form of the equation y = 4.094x + 6.255 where x is the number of sessions the patient had after their recovery. The most likely answer to this is "Before beginning recovery, patients can walk about 6 min on a treadmill." Because at x = 0, y would be equal to 6.255 which is equivalent to 6 minutes before starting the session
