Distance/Midpoint Formula (Junior Cert Mathematics): Quizzes

$\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

5 units

Brackets, exponents, then addition

To avoid mistakes, especially with negatives

$\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$

The point exactly halfway between 2 points

$(5, 5)$

Add the $x$-coordinates and divide by 2

$5$

$x_1, y_1, x_2, y_2$ from the points
