1.5.2 Gradients of parallel and perpendicular lines

For points (x1,y1)(x_1,y_1)(x1​,y1​) and (x2,y2)(x_2,y_2)(x2​,y2​), the gradient is [...]\text{[...]}[...].

A

Non-vertical lines are parallel when m1=m2\boxed{m_1=m_2}m1​=m2​​.

B

For points (x1,y1)(x_1,y_1)(x1​,y1​) and (x2,y2)(x_2,y_2)(x2​,y2​), the gradient is m=y2−y1x2−x1\boxed{m=\frac{y_2-y_1}{x_2-x_1}}m=x2​−x1​y2​−y1​​​.

C

−32-\frac{3}{2}−23​

D

A horizontal line has gradient 0\boxed{0}0​, while a vertical line has an undefined gradient.
