Answer Text:
Parallel lines have the same gradients e.g. Y = 2x +7 and 𝑦 = 2𝑥 − 9 Both lines have the same gradient which is 2 hence they are parallel.
Example 1
Find the equation of a line parallel to a line whose equation is y =3x + 4 and passes through point A (2, 3).
Example 2
Find the equation whose x-intercept is -4 and its parallel to the line passing through the points A (-3,3) and B(4,5).
