Question

1. what is the midpoint between the coordinates (-3, 7) and (9, -5)? (1.5, 3) (6, 2) (3, 1) (-6, -2)

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 $x_1=-3,y_1 = 7,x_2=9,y_2=-5$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-3 + 9}{2}=\frac{6}{2}=3$

Step3: Calculate y - coordinate of mid - point

$y=\frac{7+( - 5)}{2}=\frac{7 - 5}{2}=\frac{2}{2}=1$

Answer:

(3, 1)
