Question

Find the distance between (-1,3) and
12,4).

Answer 1

10
`√(17)` or 13.04

Explanation:

Equation for distance between two points =
`√((x2- x1)^2+(y2- y1)^2)`

For points (-1, 3) , (12, 4)

x1 = -1

x2 = 12

y1 = 3

y2 = 4

Slot in the values

`√((12-(-1))^2 + (4-3 )^2)`

=
`√((13)^2 + (1)^2)`

=
`√(169+1)`

=
`√(170)`

=
`√(10* 17)`

= 10
`√(17)` or 13.04
