Question

find the midpoint between a(-5, 25) and b(7, 15)
midpoint=( , )

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 $x_1=-5,y_1 = 25,x_2 = 7,y_2=15$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-5 + 7}{2}=\frac{2}{2}=1$.

Step3: Calculate y - coordinate of mid - point

$y=\frac{25+15}{2}=\frac{40}{2}=20$.

Answer:

$(1,20)$
