the physical quantity is distance and unit is meters
The radial velocity ie velocity towards or away from your starting point. It is NOT the ordinary speed or velocity because you can run in a circle around your starting point at top speed but the distance will not change so the slope of the distance time graph will be zero.
In a graph, the rise of a line usually represents an increase of some quantity. What that quantity is must be read off the graph's axes.
If time is the x-axis as expected then the x-intercept would be zero movement of the velocity.
The distance travelled over the time period represented by the area under the v-t graph between the end points.
A velocity time graph is still a velocity time graph - no matter the degree of detail that you look at it.
Velocity is the slope of the line on a D-t graph
It represent the distance covered is 40 metre.
Mass, possibly.
velocity.
well, the area under the curve between a time interval is equal to the distance traveled on that specific time interval. So one quantity is distance. As for another quantity, the answer would be velocity, but I think they may want a less obvious answer. A quantity out side of velocity could be instantaneous acceleration. This is given by the slope of the the tangent line to the velocity-time graph. Hope this helps you answer your question. Though I think the most simple way to understanding why is to take a course of calculus.

The distance covered in the direction of motion or the opposite direction. Distance covered in the transverse direction is not included.
a negative slope this is for my e2020 home boyz

Acceleration.

Distance travelled (displacement). Distance = velocity/time, so velocity * time = distance. Likewise, x = dv/dt so the integral of velocity with respect to time (area under the graph) is x, the distance travelled.
