दिलेल्याप्रमाणे:

(-6, y) आणि (18, 6) या दोन बिंदूंमधील अंतर 26 एकक आहे.

सूत्र:

D = \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)

जिथे, 

दोन बिंदू (x1, y1) आणि (x2, y2) मधील अंतर D एकक आहे.

गणना:

दोन बिंदूंमधील अंतर = 26 एकक

पहिल्या निर्देशांकचे मूल्य = (x1, y1) = (-6, y)

दुसर्‍या निर्देशांकचे मूल्य = (x2, y2) = (18, 6)

दिलेल्या प्रश्नानुसार,

⇒ D = \(\sqrt{(18-(-6))^2 + (6-y)^2} \)

⇒ 26 = \(\sqrt{(24)^2 + (6-y)^2} \)

समीकरणाच्या दोन्ही बाजूंचे वर्ग घेतल्यावर.

⇒ 676 = 242 + (6 - y)2

⇒ 676 = 576 + (6 - y)2

⇒ 100 = (6 - y)2

⇒ 102 = (6 - y)2

समीकरणाच्या दोन्ही बाजूंचे वर्गमूळ घेतल्यावर.

⇒ 10 = 6 - y

⇒ y = -4

∴ आवश्यक उत्तर -4 आहे.
