a) The distance d between the points `(x_1,y_1)` and `(x_2,y_2)` in a plane is:


So, the distance between the points `(5,4)` and `(-5,-4)` is:





`=2sqrt41` units.

b) The midpoint of the line segment joining the points `(x_1,y_1) ` and `(x_2,y_2)` is given by:

Midpoint=`(0.5(x_1+x_2), 0.5(y_1+y_2))`

So, the midpoint of those two points is at:

`(0.5(5+(-5)), 0.5(4+(-4)))`
