Question

A. 6 units B. 20 unitsC. About 4.5 units D.About 2.4 units

Answer 1

We have to use the distance formula

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

Let's replace the points (6,5) and (8,9).

`\begin{gathered} d=\sqrt[]{(9-5)^2+(8-6)^2}=\sqrt[]{4^2+2^2} \\ d=\sqrt[]{16+4}=\sqrt[]{20} \\ d\approx4.5 \end{gathered}`

Hence, the answer is C. About 4.5 units.
