For two points (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2), the straight-line gradient is [...]\text{[...]}[...].
A
It reduces the effect of drawing and coordinate-reading errors.
B
For two points (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2), the straight-line gradient is y2−y1x2−x1\boxed{\frac{y_2-y_1}{x_2-x_1}}x2−x1y2−y1.
C
It has the same instantaneous direction as the curve.
D
It would cause division by zero, which is undefined.
