Question

22.
Find the distance between the points (-5, 7) and (-1, 3).​

Answer 1

hope ot's clear and it's easy just revise the formula once

it will be all set

Answer 2

Given points,

(-5,7),(-1,3)

$distance = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} } \\ = \sqrt{( - 1 + 5)^{2} + (3 - 7)^{2}} \\ = \sqrt{ {4}^{2} + {4}^{2} } \\ = \sqrt{16 + 16} \\ = \sqrt{32} \\ = 4 root 2$

Explanation:

Here we saw (-5,7),(-1,3).

-5 is x base 2 and 7 is base 1 .

-1 is y base 2 and 3 is base 1.

when we get 16+16=32

we does not get perfect square 32. 16×2=32

now,we get perfect square root 16=4

4 root 2.

we get answer.
