Question

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

Answer 1

`d=5`

Explanation:

Distance Formula:
`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

Simply plug in the 2 coordinates into the distance formula to find distance d:

`d=√((3-(-1))^2+(4-1)^2)`

`d=√((3+1)^2+(3)^2)`

`d=√((4)^2+9)`

`d=√(16+9)`

`d=√(25)`

`d=5`
