1.2.3 Co-ordinate geometry in the x, y plane

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

A

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​​​.

B

−32-\frac{3}{2}−23​

C

−43-\frac{4}{3}−34​

D

A vertical line has an undefined gradient because its calculation requires division by zero.
