Question

Distance versus time is plotted and a best-fit line is found to be y= 0.098 x+ 0.01. what are the units of the slope 0.098?

Answer 1

The complete question in the attached figure

we know that
slope m=(y2-y1)/(x2-x1)
the unit of the y coordinates is the distance
the unit of the x coordinates is the time
so
the slope is equal to the speed
units of the slope=units of distance/units of time

therefore

the answer is the option  m/s
