Question

Find BA if B(-3,-1) and A(0,1). Round to the nearest tenth.

Answer 1

`BA=√(13)`

Explanation:

We are given two point B(-3,-1) and A(0,1)

We need to find distance BA

Using distance formula of two coordinate

`D=√((x_2-x_1)^2+(y_2-y_1)^2)`

Where,

`(x_1,y_1)\rightarrow (-3,-1)`

`(x_2,y_2)\rightarrow (0,1)`

Now we substitute points into formula and we get BA

`BA=√((0-(-3))^2+(1-(-1))^2)`

`BA=√((0+3)^2+(1+1)^2)`

`BA=√(3^2+2^2)`

`BA=√(9+4)`

`BA=√(13)`

Thus, Distance BA would be
`√(13)`
