Step-by-step explanation:
Given
-- Midpoint
Required
Find B
This question will be solved using midpoint formula;
Where
Substitute these values in the midpoint formula;
By comparison; we have:
-- (1)
-- (2)
Solving (1)
Multiply both sides by 2
Subtract 4 from both sides
Solving (2)
Multiply both sides by 2
Subtract 8 from both sides
