Solve problems involving gradients of parallel and perpendicular lines
Elaborations
solving problems using the fact that parallel lines have the same gradient and conversely that if two lines have the same gradient then they are parallel
solving problems using the fact that the product of the gradients of perpendicular lines is –1 and conversely that if the product of the gradients of two lines is –1 then they are perpendicular
