Question

What's the distance between P(-4,3) and Q(6,1). Round to the nearest tenth

Answer 1

`d=10.2`

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=√((6-(-4))^2+(1-3)^2)`

`d=√((6+4)^2+(-2)^2)`

`d=√((10)^2+4)`

`d=√(100+4)`

`d=√(104)`

`d=2√(26)`

`d=10.198`

`d=10.2`
