Question

State the distance formula .
State the midpoint formula.
Help me please I don't understand this question well both.

Answer 1

distance formula =square root (x2-x1)^2 + (y2-y1)^2

Answer 2

\[D =\sqrt{\left(x_2 - x_1\right)^2 + \left(y_2 - y_1\right)^2}\]

Answer 3

\[M = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)\]
