👉 In this playlist, you will learn how to graph a linear equation in standard form, slope-intercept form, as well as when the slope and y-intercept are provided. In addition to graphing linear ...

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.

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...
