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−x1y2−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.
