Slope is equal to the change in y divided by the change in x (also known as "rise over run"). If a slope is 18 , then it "rises" 18 units, for every 1 unit of x.
A horizontal line on a phase change graph means there has been no change. Often longer periods of research are needed to see significant change.
It means there is no movement towards or away from the point from which distances are measured - usually the origin. The object can be moving in a transverse direction at any speed and the graph would not show it.
A straight horizontal one does.
It means there is no velocity - it is at rest and nothing is moving. The slope of the line is velocity - a horizontal line is zero slope = zero velocity
x axis means the horizontal line and y axis means the vertical line
It marks the origin - the point where the horizontal and vertical axes cross.
A horizontal line on a phase change graph means there has been no change. Often longer periods of research are needed to see significant change.
Horizontal means going left and right: ___ Vertical means going up and down: |
It means that the variable plotted on the vertical axis increases as the one plotted on the horizontal axis increase.
I believe you are confusing "horizontal" with "vertical". "Vertical" means "from top to bottom", or "upright". "Horizontal" means "from left to right", or "lying".
The vertical axis in a plane coordinate graph
Vertical means up or down, horizontal means left or right (or forward or backwards, but without changing the altitude).
The change in y over the change in x. Y is a vertical axis, while x is a horizontal axis. Change in means you find the diference of the values for either the y or x values, which are obtained from their point on the graph. Ex] (x1,y1) (x2,y2) slope=. It is rise over run.
the slope More often called the gradient in maths - but means the same. It's also given by differentiating the equation.
There is no such thing as exactly vertical because either it is vertical or it is not. You cannot have approximately vertical - it is not vertical, then. Vertical means at 90 degrees to the horizon (or horizontal).
Diagonal means across at an angle, not horizontal or vertical.
It means that the function is constant.
