Expert Solution
Step 1
In a velocity vs time graph, a straight line with a slope indicates either a increasing velocity or decreasing velocity.
Mathematically, Velocity is given by
v = Δx/ Δt
i.e the rate of change of displacement is called velocity
Thus, the above formula implies that for increasing velocity the slope is positive, and for decreasing velocity, the slope is negative.
Speaking along the direction of displacement, the y-axis signifies the sense of displacement. Below the x axis, the sense is negative while above the x-axis, the sense is positive.
