1.5.5 Form the equation of a straight line

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

A

The gradient perpendicular to a line of gradient mmm is −1m\boxed{-\frac{1}{m}}−m1​​.

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

Its gradient requires division by zero, so it is undefined.

D

C=1.2d+4.5C=1.2d+4.5C=1.2d+4.5
