A horizontal line on a distance-time graph shows **that the object is stationary (not moving because the distance does not change)** A sloping line on a distance-time graph shows that the object is moving. In a distance-time graph, the slope or gradient of the line is equal to the speed of the object.

## What does horizontal line on a displacement time graph represent?

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!

## What does the 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.

## What is an example of a horizontal line?

Examples. Look at a wall, and look down to where that wall meets the floor. That **intersection** is a horizontal line. Other examples of horizontal lines we may see every day are the following: the line separating the sky from the land across a clear plain or the line separating the sky from the water at the beach.

## Is a horizontal line positive or negative?

The slope of **a line can be positive, negative, zero, or undefined**. A horizontal line has slope zero since it does not rise vertically (i.e. y_{1} − y_{2} = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x_{1} − x_{2} = 0). because division by zero is an undefined operation.

## What does it mean when velocity is a horizontal line?

On a velocity-time graph a horizontal (flat) line indicates **the object is travelling at a constant speed**. A straight diagonal line indicates the object’s velocity is changing.

## What does a line curving upwards and a distance time graph represent?

**If the speed of an object changes, it will be accelerating or decelerating** . This can be shown as a curved line on a distance-time graph. If an object is accelerating or decelerating, its speed can be calculated at any particular time by: drawing a tangent to the curve at that time.

## How is horizontal line?

A horizontal line is **one that goes from left to right across the page**. This is because horizontal lines are parallel to the horizon. … It comes from the word “horizon”, which refers to the visible line that separates the earth from the sky.

## Is horizontal up and down or side to side?

The terms vertical and horizontal often describe directions: **a vertical line goes up and down**, and a horizontal line goes across. You can remember which direction is vertical by the letter, “v,” which points down.

## What is the other name of horizontal line?

level | parallel |
---|---|

complanate | perfectly vertical |

perfectly horizontal |
on a line |

of same height | parallel with the ground |

dead flat | lined up |

## What is horizontal picture?

Horizontal photographs are **photographs that are wider than they are tall**. Vertical photographs are photographs that are taller than they are wide. Cameras are designed to take one type of photograph — horizontal. This follows the way that human beings see the world.

## What does the horizontal line test prove?

The horizontal line test is a convenient method that **can determine whether a given function has an inverse**, but more importantly to find out if the inverse is also a function. … We say this function passes the horizontal line test.

## How do you tell if a line is horizontal or vertical?

The number “zero” exists, so **horizontal lines do** indeed have a slope. But vertical lines don’t have any slope; “slope” simply doesn’t have any meaning for vertical lines.

## What is the equation of a horizontal line?

The equation of a horizontal line passing through a point (a, b) is **y = b**, where ‘b’ is constant because in the equation y = mx + b, where ‘b’ is the y-intercept, there is no change in the value of y on the horizontal line and the slope is zero, therefore, the equation of a horizontal line is y = b.

## What does a horizontal line mean on a acceleration time graph?

A horizontal line on a speed-time graph represents a steady speed. This can also be called a constant or uniform speed. A sloping line on a speed-time graph represents **an acceleration** . The sloping line shows that the speed of the object is changing.

## What is the acceleration of a horizontal line?

The slope of a horizontal line **is zero**, meaning that the object stopped accelerating instantaneously at those times. The acceleration might have been zero at those two times, but this does not mean that the object stopped.
