How Do You Plot a Position-Time Graph with Subtle Curves?

[gohanssj2a99]

Homework Statement

Plot your position-time info on a graph. Draw a smooth curve that fits the data closely

Homework Equations

t(s)---D(mm)(Position Data)
0.00---0mm
0.20---18mm
0.40---37mm
0.60---58mm
0.80---82mm
1.00---101mm
1.20---115mm

The Attempt at a Solution

I am not sure but is it asking for a curve of best fit because when i plotted the points it looked more linear than curved

Yes, it looks kind of linear, but not quite. You can not use a straight line fit. The curve is subtle.
