If a graph shows time on the horizontal axis and speed on the vertical
axis, a straight horizontal line across the graph would indicate?

a. no motion
b. constant speed
c. steady acceleration
d. maximum speed

Hi again!!


A straight horizontal line across the graph indicates:

b. constant speed.


In effect, the horizontal line in the graph indicates that for every
value of the horizontal axis (time) corresponds the same value on the
vertical axis (speed), i.e. the same speed for every time, that is a
constant speed.


I hope that this helps you. Feel free to request for a clarification
if you need it.

The answer would be b. because the constant speed will be a straight line.
