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−x1y2−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
