The graph of --------------- is a straight line parallel to X axis.
y = a + x
y = ax
y = a - x
y = a
y = a, is the equation of the line parallel to x axis.
The graph of y = a is
(a) the x - axis
(b) the y - axis
(c) a line parallel to y - axis
(d) a line parallel to x - axis
For uniform motion :
(a) the distance-graph is a straight line parallel to the time axis.
(b) the speed-time graph is a straight line inclined to the time axis.
(c) the speed-time graph is a straight line parallel to the time axis.
(d) the acceleration-time graph is a straight line parallel to the time axis.
