Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFमाना कि परावर्तित बिंदु (x, y) है।
तब मध्य बिंदु (-1, 3) और (x, y) है जो (x-1/2, y + 3/2) है, अवश्य रेखा x = -4 मिलती है।
⇒ x – 1/2 = -4
⇒ x = -8 + 1 = -7
चूंकि मूल और परावर्तित बिंदु को जोड़ने वाली रेखा x = -4 पर है, इसलिए इसकी ढलान 0 होगी।
⇒ [y – 3]/[(-7) – (-1)] = 0
⇒ y – 3 = 0
⇒ y = 3
∴ परावर्तित बिंदु (-7, 3) है।
