Determine the acceleration of the marble from the straight line equation you calculated in question 2.

So the equation i found in Q2 was y=9.84x+6.79

How do i figure out acceleration from this? please help!

If y is displacement, and x is time...I have no idea what your equation is...

then acceleration is zero. Notice the change in position is directly dependent on x, meaning constant velocity.
y is velocity and x is time.
thank you :)
