Practical examples demonstrate how to write the equation of a line given different sets of information, such as two points, a point and the slope, or a graph. The video also covers parallel and ...
Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...
👉 Learn how to write the equation of a line in a point-slope form. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e. there are no exponents in its variable(s)).
