A segment has endpoints at (-11, 12) and (8, -5). What is the x-coordinate of the midpoint of that segment? Enter your answer as a decimal.

Question

mathstudent55 · Answer

The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.
In other words, add the x-coordinates of the endpoints and divide by 2.

triciaal · Answer

your x values are -11 and 8
what is the absolute value of -11 and  + 8 ? means just actual units 
what is half of that?  mid-point is half-way
now if you start at -11 and add the number of units for 1/2 way what is the x value?
enter your answer as a decimal.
