Writing equations of lines is a fundamental skill in algebra and geometry, essential for understanding linear relationships and graphing. This video provides a thorough guide to writing 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 ...

Master the process of finding the equation of a tangent line in calculus with this step-by-step tutorial. Learn how to calculate derivatives, apply the point-slope formula, and solve problems ...

All straight line graphs have an equation that can be written in the form 𝑦 equals 𝑚𝑥 add 𝑐, where 𝑚, the coefficient of the 𝑥 term, is the gradient or slope of the line. The constant, 𝑐, is ...

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.
