Starting point: The y-intercept tells you the object’s starting point. If an object starts at the measuring device, then its’ y-intercept is 0. If it starts 3 meters away, then its y-intercept is 3 m. Intersection of 2 lines tells you when 2 objects have the same position.

## Q. What speed is shown as a straight line on a distance time graph?

‘Straight lines’ on a distance-time graph tell us that the object is travelling at a constant speed. Note that you can think of a stationary object (not moving) as travelling at a constant speed of 0 m/s. On a distance-time graph, there are no line sloping downwards.

## Q. What goes on the Y axis of a distance time graph?

On a distance time graph, the distance will always be the dependent variable on the y- axis. Time is the independent variable and will always be placed on the x-axis. The lines on the graphs can tell you many different things. The slope of a line (steepness) can tell you speed.

## Q. Can time ever be on the y-axis?

In principle, time can be placed on the y-axis. This is, however, not very common when making graphs and it is primarily only done in special relativity when making Minkowski diagrams or spacetime diagrams.

## Q. What does a flat horizontal line represent on a distance time graph?

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!

## Q. What does a horizontal line on a graph mean?

In more simple terms, a horizontal line on any chart is where the y-axis values are equal. If it has been drawn to show a series of highs in the data, a data point moving above the horizontal line would indicate a rise in the y-axis value over recent values in the data sample.

## Q. What would be the horizontal line in a position time graph means?

In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.

## Q. What does a distance-time graph look like?

A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. Time is plotted on the X-axis.

## Q. What is the horizontal line?

Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

Now that we are familiar with the coordinate plane, it's time to learn more about lines, as these are the simplest things to graph. Lines have slopes, and th…
