Answer:
<h3>The option B) is correct</h3><h3>Therefore the coordinate of BStep-by-step explanation:
Given that the midpoint of segment AB is (4, 2). The coordinates of point A is (2, 7).
<h3>To Find the coordinates of point B:</h3>- Let the coordinate of A be
is (2,7) respectively
- Let the coordinate of B be
- And Let M(x,y) be the mid point of line segment AB is (4,2) respectively
- The mid-point formula is
- Now substitute the coordinates int he above formula we get
- Now equating we get
Multiply by 2 we get Multiply by 2 we get
Subtracting 2 on both
the sides Subtracting 7 on both the sides
Rewritting the above equation Rewritting the equation
