No.
No, they are not really close.
They are not the same due to the inaccuracies in the readings I assume.

.3, 10.6 cm/s^2
.6, 22.2 cm/s^2

The 1st number is the ramp slope, it’s unitless. The 2nd number is the acceleration (averaged means).
** **
0
.8
This is the slope, there are no units.
This is the acceleration, in cm/s^2.

.1, .8
I made a straight line fit on the graph and made the measurements.

The 1st 3 lines show 1st the slope, then the lower range of the acceleration, the last 3 lines show 1st the slope, then the upper range of the acceleration.
** **
Yes, the graph is increasing.
Yes, the line comes close to the points.
** **
I used slope .2 instead of .1 since my line intercepts at .1.
8cm/s^2, .2, 40cm/s^2
Slope was obtained by dividing the rise by the run. The 1st number is the rise, the 2nd, the run, the 3rd is the slope. (.2, 8)
I believe your slopes should be .03, .06 and .09, not .3, .6 and .9.
This will affect your last few answers and should be very easy to correct.
** **
8cm/s^2, .15, 53.3cm/s^2
Slope was obtained by dividing the rise by the run. The 1st number is the rise, the 2nd, the run, the 3rd is the slope. (.15, 8)

Mr. Smith,
Can you give me an estimate as to where I stand grade wise in the class right now?
Very good, except for a few easily-corretable errors related to your ramp slopes.
