In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...

The slope of a line, often denoted by the letter m, is defined as the ratio of the vertical change (rise) to the horizontal ...

Predicting Values: Once you have a linear equation that represents a relationship, you can use it to predict values. For ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
