Question 1046533
The origin lies midway between ({{{1}}},{{{3}}}) and ({{{-1}}},{{{-3}}}).

to see that, use midpoint formula:

{{{x}}} Coordinate of Midpoint ={{{(x[1]+x[2])/2}}}
{{{x}}} Coordinate of Midpoint ={{{(1+(-1))/2}}} 
{{{x}}} Coordinate of Midpoint ={{{(1-1)/2}}}

{{{x}}} Coordinate of Midpoint ={{{0/2}}}

{{{x}}} Coordinate of Midpoint ={{{0}}}

{{{y}}} Coordinate of Midpoint ={{{(y[1]+y[2])/2}}}
{{{y}}} Coordinate of Midpoint ={{{(3+(-3))/2}}} 
{{{y}}} Coordinate of Midpoint ={{{(3-3)/2}}}

{{{y}}} Coordinate of Midpoint ={{{0/2}}}

{{{y}}} Coordinate of Midpoint ={{{0}}}

so, midpoint is at ({{{0}}},{{{0}}}) which is origin

The origin lies midway between ({{{1}}},{{{3}}}) and ({{{-1}}},{{{-3}}}):{{{true}}}
