Question

Use the Pythagorean Theorem to determine the distance between points A(5, 3) and B(-3, -3). 1) 64
2) 36
3) 100
4) 10

Answer 1

Formula
\[Distance= \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}} \]
insert yout values\[Distance= \sqrt{(5--3)^{2}+(3--3)^{2}} \]
\[= \sqrt{8^{2}+6^{2}} \]
\[= \sqrt{64+36} \]
\[= \sqrt{100}=10 \]
