Question

find the midpoint between: (11, -7) and (-9, -1)

Explanation:

Step1: Recall mid - point formula

The mid - point formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$. Here $x_1=11,y_1 = - 7,x_2=-9,y_2=-1$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{11+( - 9)}{2}=\frac{11 - 9}{2}=\frac{2}{2}=1$.

Step3: Calculate y - coordinate of mid - point

$y=\frac{-7+( - 1)}{2}=\frac{-7 - 1}{2}=\frac{-8}{2}=-4$.

Answer:

$(1,-4)$
