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

Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...

Another way of looking at slope of a line is looking at it as an equation. We talked about what it meant for rise over run before. So what we will talk about how is that slope m equals the change in y ...

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.
