Matching linear equations with their corresponding graphs is a fundamental skill in algebra and a crucial stepping stone 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.
The slope of a line, often denoted by the letter m, is defined as the ratio of the vertical change (rise) to the horizontal ...
