Question

Find the distance between the pair of points (2,9) and (3,8).

Answer 1

Answer:

$\sqrt{2}$ units

Step-by-step explanation:

To find the distance between a pair of points, use the distance formula, $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$. Substitute the x and y values of (2,9) and (3,8) into the formula and simplify:

$d = \sqrt{(8-9)^2+(3-2)^2} \\d = \sqrt{(-1)^2+(1)^2} \\d = \sqrt{1+1} \\d= \sqrt{2}$

So, the distance is $\sqrt{2}$ units.
