Answer:

(1/2,-5/2)

Explanation:


( - 3 + 4 )/(2) = (1)/(2) \\ ( - 4 + - 1)/(2) = ( - 5)/(2)

Answer:


\displaystyle \left((1)/(2),-(5)/(2)\right)

Explanation:

Given a segment defined by the points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:


\displaystyle x_m=(x_1+x_2)/(2)


\displaystyle y_m=(y_1+y_2)/(2)

The segment CD is defined by the points in graph C(-3,-4) and D(4,-1). The midpoint is:


\displaystyle x_m=(-3+4)/(2)=(1)/(2)


\displaystyle x_m=(1)/(2)


\displaystyle y_m=(-4-1)/(2)=(-5)/(2)


\displaystyle y_m=-(5)/(2)

Thus, the midpoint is:


\mathbf{\displaystyle \left((1)/(2),-(5)/(2)\right)}
