Question

PB is a line segment on a number line. It has endpoints at -2 and 12. What is the coordinate of its midpoint.

Answer 1

so we know that a number line just exists on the horizontal plane, so we know that our two points are x = =2 and x = 12, so the mid point can actually just be found by averaging these two points,

so average = ((-2) + (12))/2
so = (10)/2
= 5
therefore the midpoint is at 5

Answer 2

thanks!
