Question

find the coordinates of the point C, halfway between the points A(5,1) and B(-2,7)

Answer 1

The x-coordinate of C is the average of the x-coordinates of A and B.
Likewise for the y-coordinate.

For example:
P(4,6), Q(10,12), M is the mid-point.
M((4+10)/2,(6+12)/2)=M(7,9)

Answer 2

use formula for mid points...that is..
(\[(\frac{ x2+x1 }{ 2 },\frac{ y2+y1 }{ 2 })\]

Answer 3

so it will be as follows..
\[(\frac{ 5-2 }{ 2 },\frac{ 7+1 }{ 2 })\]
\[=(\frac{ 3 }{ 2 },4)\]
