Question

1 directions - use the midpoint formula to find the midpoint between the following points (-4,9) and (2,1) midpoint formula: $\left(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2}\
ight)$ midpoint = $-1\frac{1}{2}$

Explanation:

Step1: Identify the coordinates

Let $(x_1,y_1)=(-4,9)$ and $(x_2,y_2)=(2,1)$.

Step2: Calculate the x - coordinate of the mid - point

$x=\frac{x_1 + x_2}{2}=\frac{-4 + 2}{2}=\frac{-2}{2}=-1$.

Step3: Calculate the y - coordinate of the mid - point

$y=\frac{y_1 + y_2}{2}=\frac{9+1}{2}=\frac{10}{2}=5$.

Answer:

$(-1,5)$
