When we analyze this diagram in xy coordinate system we can conclude that the line AB is intercepting x-axis at point (2.5, 0 ) and that is the midpoint of the line AB. We will use formulas for the middle point of the line:
x= ( x_(1) + x_(2) )/(2) y= ( y_(1) + y_(2) )/(2)
2.5= (1+ x_(2) )/(2)When we solve the equation: x2=4.
0= (5+ y_(2) )/(2) y2=-5
Answer: The coordinates of point B are (4, -5).
