In this case both the slope and the y intercept are known and the equation can be written directly. For example if the slope is -2 and the y intercept is (0,6), then the equation is In this case the ...

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into the ...

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 ...

This is based on paper Use of the Hough Transformation To Detect Lines and Curves in Pictures by Richard O. Duda and Peter E. Hart. y = m * x + b where, m = gradient / slope of line ...
