Question

describe and correct the error a student made in finding the midpoint of $overline{cd}$ with $c(-4,5)$ and $d(-1,-4)$. the student did not add the x - and y - coordinates when calculating the midpoint. the correct answer is (type an ordered pair, using integers or fractions.)

Explanation:

Step1: Formula de punto medio

La fórmula para el punto medio de dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$. Aquí $x_1=-4,y_1 = 5,x_2=-1,y_2=-4$.

Step2: Calcular la coordenada x del punto medio

$\frac{-4+( - 1)}{2}=\frac{-4 - 1}{2}=\frac{-5}{2}$

Step3: Calcular la coordenada y del punto medio

$\frac{5+( - 4)}{2}=\frac{5 - 4}{2}=\frac{1}{2}$

Answer:

$(-\frac{5}{2},\frac{1}{2})$
