The rate at which an ordinate of a point of a line on a coordinate plane changes with respect to a change in the abscissa. Slope is a value that describes the steepness and direction of a line. So let me write this down.
And the convention is is we measure the increase in vertical for a given in increase in horizontal.
Understand what slope is and how to calculate slope when given a graph. The slope of a line in the plane containing the x and y axes is generally represented by the letter m and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate between two distinct points on the line. Horizontal line equation vertical line equation parallel lines perpendicular. In variable format it is commonly represented by the letter m.
