Between the points (5,4) and (-5,-4) find:

a) The distance - use sqrt (N)

b) The midpoint - use .5 for 1/2

### 1 Answer | Add Yours

The distance D between two points can be calculated as;

`D = sqrt((5-(-5)^2)+(4-(-4))^2) = sqrt164 = 4sqrt11`

*So the distance between to points is `4sqrt11` .*

The midpoint M between the two points is given by;

`M = (5+(-5))xx0.5,(4+(-4))xx0.5 = (0,0)`

**So the midpoint is the origin (0,0)**
