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:[tex]x= \frac{ x_{1} + x_{2} }{2}
y= \frac{ y_{1} + y_{2} }{2}
[/tex][tex]2.5= \frac{1+ x_{2} }{2} [/tex]When we solve the equation: x2=4.[tex]0= \frac{5+ y_{2} }{2} [/tex] y2=-5
Answer: The coordinates of point B are (4, -5).
