When a baseball is tossed directly upward, what is the slope of a plot of its acceleration versus time during the upward flight?

plot has constant positive slope

plot has constant negative slope

plot has zero slope

I think it is zero slope

no, the acceleration is a constant: -9.8m/s^2 or -32ft/s^2, due to gravity
If accerlation is constant, then that would show a straight line on the graph, correct? So that line has a slope=0.
The plot would have a zero slope. That is the answer.
