Question

Find the distance between the pair of points (4,9) and (12,3)

Answer 1

The formula for the distance between point (x_1,y_1) and (x_2,y_2) is,

`d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}`

Determine the distance between points (4,9) and (12,3) by using distance formula.

`\begin{gathered} d=\sqrt[]{(12-4)^2+(3-9)^2} \\ =\sqrt[]{64+36} \\ =\sqrt[]{100} \\ =10 \end{gathered}`

So distance between the two points is 10.
