Lines which are parallel have the same gradient. For example, \(\text{y = 2x + 1}\) and \(\text{y = 2x - 2}\) will be parallel because they both have a gradient of 2. We want to determine if the ...

Image caption, This image has one pair of parallel lines and one transversal. The diagonal line is a transversal as it is crossing the pair of parallel lines. When two lines intersect, the ...
