Question

Part B

plot point C(2,7). If M is the midpoint of CD what are the coordinates of D

Answer 1

The midpoint of CD is
`((2+a)/(2),\ (7+b)/(2))`.

Explanation:

Consider a line CD.

The point C is (2, 7).

Assume that the point D is, (a, b).

The formula to compute the midpoint is:

`(x,y)=((x_(1)+x_(2))/(2),\ (y_(1)+y_(2))/(2))`

Compute the midpoint of CD as follows:

`(x,y)=((x_(1)+x_(2))/(2),\ (y_(1)+y_(2))/(2))`

`=((2+a)/(2),\ (7+b)/(2))`

Thus, the midpoint of CD is
`((2+a)/(2),\ (7+b)/(2))`.
