Remember that to find the equation of a straight line you need to know its gradient and a point on the line. In some instances you are told the value of the gradient, however there are times where you ...
👉 Learn how to write the equation of a line that is parallel to a given line. 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 ...
For parallel lines, the slopes are equal. Thus given the equation of a line and a point through which the line parallel to the given line passes, then the slope of the second line is equal to 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 ...
