Question

Helppp please i don’t understand

Answer 1

Here's the Solution,

let's take :

• x1 = 7
• x2 = 3
• y1 = 5
• y2 = 2

now,

=》

`d = \sqrt{(x2 - x1) {}^(2) + (y2 - y1) {}^(2) }`

=》

`d = \sqrt{(3 - 7) {}^(2) + (2 - 5) {}^(2) }`

=》

`d = \sqrt{( - 4) {}^(2) + ( - 3) {}^(2) }`

=》

`d = √(16 + 9)`

=》

`d = √(25)`

=》

`d = 5`

So, distance between the points is 5 units
