Question

Part B

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

Answer 1

Answer:

The midpoint of CD is $(\frac{2+a}{2},\ \frac{7+b}{2})$.

Step-by-step 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:

$(x,y)=(\frac{x_{1}+x_{2}}{2},\ \frac{y_{1}+y_{2}}{2})$

Compute the midpoint of CD as follows:

$(x,y)=(\frac{x_{1}+x_{2}}{2},\ \frac{y_{1}+y_{2}}{2})$

        $=(\frac{2+a}{2},\ \frac{7+b}{2})$

Thus, the midpoint of CD is $(\frac{2+a}{2},\ \frac{7+b}{2})$.
