Question

Find the distance between the points P(1,-1) and Q (5,2)​

Answer 1

Answer:

5 units

Explanation:

by using distance formula

Answer 2

Answer:

$pq \: = \sqrt{(x1 - x2) {}^{2} + (y1 - y2) {}^{2} } \\ pq = \sqrt{ {(5 - 1)}^{2} + {(2 + 1)}^{2} } \\ pq = \sqrt{16 + 9} \\ pq = \sqrt{25} \\ pq = 5 \: units$

hope it helps
