In the standard (x,y) coordinate plane, what are the coordinates of the midpoint of a line segment whose endpoints are (–3,0) and (7,4) ?
A. (2,2)
B. (2,4)
C. (5,2)
D. (5,4)
E. (5,5)



Answer :

[tex]A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\midpoint\ AB:\left(\frac{x_A+x_B}{2};\ \frac{y_A+y_B}{2}\right)\\\\-------------------\\\\(-3;\ 0);\ (7;\ 4)\\\\midpoint:\left(\frac{-3+7}{2};\ \frac{0+4}{2}\right)\to\left(\frac{4}{2};\ \frac{4}{2}\right)\to(2;\ 2)\\\\Answer:A[/tex]
