It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
If the axes are time/distance then, and only then, it means a constant velocityIf not, then this Q doesn't have enough data to A
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
A straight line graph (on the cartesian or coordinate plane).
Standing still or not moving
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
Look for the key to the symbols on your graph, which will explain the straight line.

When there is a curved line going upwards on a graph it means the distance is increasing
y axis
A straight line graph (on the cartesian or coordinate plane).
With distance on the x axis and time on the y axis a steep line would indicate a short distance traveled over a long period of time, depending on the scale of the graph.
Standing still or not moving
Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
If you mean: y = 3x+7 then it is a straight line equation that can be plotted on the Cartesian plane
