1. Section Formula:-

• If a point divides a line segment in a ratio m1:m2 the. the coordinates of that point will be,

$\\ \bf\mapsto X = \frac{m1x_2 + m2x_1}{m1 + m2}. \\ \\ \bf\mapsto Y = \frac{m1y_2 + m2y_1}{m1 + m2}.$

2. Mid - Point Formula:-

• If a point divides a line segment in two equal parts then the coordinates of that point will be,

$\\ \bf\mapsto X = \dfrac{x_1 + x_2}{2}. \\ \\ \bf \mapsto Y = \frac{y_1 + y_2}{2}.$
