Respuesta :
we can simply just draw them, notice it is a vertical line
Check the picture below.

For this case we have that by definition, the midpoint is given by:
[tex](\frac{x_ {1} + x_ {2}} {2}, \frac {y_ {1} + y_ {2}} {2})[/tex]
We have the following extreme points of a line:
[tex](x_ {1}, y_ {1}) :( 0,0)\\(x_ {2}, y_ {2}) :( 0, -12)[/tex]
Substituting in the formula we have:
[tex](\frac{0 + 0}{2}, \frac {0-12} {2})\\(\frac {0} {2},\frac {-12} {2})\\(0, -6)[/tex]
We have that the midpoint is (0, -6)
Answer:
(0, -6)
