Question

Find the distance between the point P( -1, 1 ) and Q( 5, -7 )?​

Answer 1

By distance formula

Distance PQ = root(6^2 + 8^2) = root(36+64) = root(100) = 10

Answer 2

Answer:

7√37

Step-by-step explanation:

We know that,

$Distance \: between \: two \: points \: = \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} } \\= \sqrt{(1 - ( - 1)) {}^{2} + ( - 7 - 5) {}^{2} } \\ = \sqrt{(2) {}^{2} + ( - 12) {}^{2} } \\ = \sqrt{4 + 144} \\ = \sqrt{148} \\ PQ = 2 \sqrt{37}$

Hope this will help you!!
