Finding The Gradient Of A Straight Line
The gradient of a line tells us how steep the line is. Lines going in this / direction have positive gradients, and lines going in this \ direction have negative gradients. The gradient can be found by finding how much the line goes up -...

What is the slope formula and where does it come from
👉 Learn all about the slope of a line. The slope of a line is the steepness of the line. The horizontal line has a zero slope while the vertical line has an undefined slope. To determine the slope of a line, we need to know the...

Algebra 46 - Parametric Equations
In order to mathematically describe a line in 3-dimensional space, we need a way to define the values of the three coordinates at every point along the line. This can be done by creating a group of "parametric equations".
