slope of the graph on first part of the motion

slope = \frac{\Delta x}{\Delta t}

slope = \frac{40 - 20}{1}

slope = 20

for next part of motion similarly

slope = \frac{\Delta x}{\Delta t}

slope = \frac{80 - 40}{1}

slope = 40

so this shows the slope of the motion is not same during two interval of time

it shows that the velocity of the motion is not constant and increasing here with time

SO this shows and accelerated motion from initial to final and the overall slope of the motion is given by

slope = \frac{\Delta x}{\Delta t}

slope = \frac{80 - 20}{2}

slope = 30
