Use the connection you found to find the coordinates of B given that M(-7, 1) is the midpoint Class 9

Question 1.

Use the connection you found to find the coordinates of B given that M(-7, 1) is the midpoint of A(3, -4) and B(x, y). Class 9

Solution:

M(-7, 1) is the midpoint of A (3, -4) and B (x, y).

∴ -7 = [latex]\frac{3+x}{2}[/latex] and 1 =[latex]\frac{-4+y}{2}[/latex]

∴ -14 = 3 + x and 2 = -4 + y

∴ x = -17 and y = 6

∴ B = (-17, 6)
