Answer

Therefore, the coordinates of point N are (8,5).

Steps

Step 1 :Use the midpoint formula: M=(x1+x22,y1+y22)

Step 2 :Substitute the given values: M=(2+x22,3+y22)

Step 3 :Simplify the equations: 5=2+x22 and 1=3+y22

Step 4 :Multiply both sides of the first equation by 2: 10=2+x2

Step 5 :Subtract 2 from both sides: x2=8

Step 6 :Multiply both sides of the second equation by 2: 2=3+y2

Step 7 :Add 3 to both sides: y2=5

Step 8 :Therefore, the coordinates of point N are (8,5).
