What does a straight line mean on a velocity time graph?
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. The general rule of thumb is if the object is going from a high speed to a low speed, it is decelerating.
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. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.
What does a undefined slope look like?
An undefined slope (or an infinitely large slope) is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is! There is no run!
How do you know if the slope is undefined?
Note that when a line has a positive slope it goes up left to right. Note that when a line has a negative slope it goes down left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined.
What is the equation of a zero slope?
The equation for a zero slope line is one where the X value may vary but the Y value will always be constant. An equation for a zero slope line will be y = b, where the line’s slope is 0 (m = 0).
What is an example of undefined slope?
A good real life example of undefined slope is an elevator since an elevator can only move straight up or straight down. It got its name “undefined” from the fact that it is impossible to divide by zero. However, it is impossible to do 5/0 because there exist no number you can multiply 0 by to get 5.
What happens when the slope is 0?
The slope of a line can be thought of as ‘rise over run. ‘ When the ‘rise’ is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it.
What is the slope of 0 6?
An undefined slope means a vertical line. The equation of the vertical line passing through (0,6) is x=0 . The y axis has the equation x=0 too, so the line and the axis intercept at all points of the y axis.
