I know that acceleration is equal to slope. or in other words rise divided by run or the average rate of change of velocity with respect to clock time. When you ask if it is possible that the acceleration is uniform is that the same thing as asking if the slope is always equal? How do you proof this.

Remember that vAve = `ds / `dt, and this is so whether acceleration is constant or not.

If acceleration is uniform, then the v vs. t graph is a straight line, and over any interval we have vAve = (vf + v0) / 2.

So if vAve is not equal to (vf + v0) / 2, then acceleration cannot be uniform.
