If and are two opposite vertices of a square, then find the equation of a side passing through
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Let ABCD be a square where A≡1,3 & C≡7,5. ∴ Equation of diagonal AC is y-53-5=x-71-7 ⇒ 3y-15=x-7 ⇒ 3y-x-8=0 ...1 ∴ Slope of AC is 13 Suppose slope of AB is m. ∵ Diagonal makes 45° with…
