In the coordinate plane,
point H has coordinates
(2,5) and is the midpoint
of the line segment GI.
The coordinate of points
G and I are (x, 12) and
(7,-2), respectively. What
is the value of x?
because (2,5) is the midpoint of GI and one of the known values was (7,-2). if u have a graphing calculator or use a graphing website, it shows (-3,12), and -3 being the missing x value.
