Question

U(11,9) and S(-12,-6). Find US

Answer 1

For this problem we can use the definition of euclidean distance given by:

`d=√((y_2-y_1)^2+(x_2-x_1)^2)`

We have these coordinates:

`U=(11,9),S=(-12,-6)`

And replacing we got:

`d=√((11+12)^2+(9+6)^2)`

And when we simplify we got:

`d=√(529+225)=√(754)`

And if we simplify we got:

`d=27.459`

The midpoint can be calculated with this formula:

`M=((x_1+x_2)/(2),(y_1+y_2)/(2))`

And replacing we got:

`M=((11-12)/(2),(9-6)/(2))`
`M=(-(1)/(2),-(3)/(2))`
