Question

How do you find the midpoint of (-1,4) and (-2,-9)?

Answer 1

The mid point `= (-1.5 , -2.5)`

Explanation:

The coordinates are:
`(-1,4) = color(blue)(x_1,y_1`

`(-2,-9) = color(blue)(x_2,y_2`

The mid point is found using formula:
`(x_1+x_2)/2 , (y_1+y_2)/2`

`= (-1+ (-2))/2 , (4 +(-9))/2`

`= (-3)/2 , (-5)/2`

`= (-1.5 , -2.5)`
