Question 45439
A pair of points is given. 
(a) plot the points in a coordiunate plane

{{{ graph( 300, 200, -6, 10, -10, 15, -1.2x+6) }}}

.
(b) find the distance between them.
{{{distance (d) = sqrt( (x1-x2)^2 + (y1-y2)^2) }}} 
{{{distance (d) = sqrt( (5-0)^2 + (0-6)^2) }}} 
{{{distance (d) = sqrt( (5)^2 + (-6)^2) }}}
{{{distance (d) = sqrt( (25) + (36)) }}}
{{{distance (d) = sqrt( (61)) }}}
d = 7.81
.
.

(c) find the midpoint of the segment joins them.
Midpoint = [ (x1+x2)/2, (y1+y2)/2 ]
Midpoint = [ (5+0)/2, (0+6)/2 ]
Midpoint = [ 5/2, 6/2 ]
Midpoint = (2.5, 3)
