In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in ...

Watch this video to learn about the equation of a straight line. Since we are given 2 points that already lie on the line, using the formula as before, we need to calculate the gradient first.

Algebra is the branch of mathematics that focuses on formulas, and one of its key concepts is the representation of linear equations, which describe straight lines. Among the various forms you can ...
