The coordinates of the endpoints of line ab are graphed in the standard (x, y) coordinate plane at (10, 14) and (4, -2). what is the y-coordinate of the midpoint of line ab?

y coordinate of midpoint of line AB is 6

Solution:

Given that endpoints of line AB is (10, 14) and (4, -2)

To find:  y-coordinate of the midpoint of line AB

The midpoint of line AB is given as:

For a containing and the midpoint is given as:

Here in this question,

So midpoint is:

Therefore y coordinate of midpoint of line AB is 6

its the fourth option
