Question

Find the distance between the points (7,
–
9) and (
–
2,
–
4).

Answer 1

7.07106781187

Explanation:

Let us use the distance formula:

`d = √((x_2 - x_1)^2 + (y_2-y_1)^2)`

x2=2

x1=7

y2=4

y1=9

`d = \sqrt{(2 - 7)^(2) + (4-9)^2}`

`d = √((-5)^2 + (-5)^2)`

`d = √(25 + 25)`

`d = √(50)`

d=7.07106781187 (round to whatever digit neccesary)

Hope this helps!!
