समीकरण (9x-10y+30=0) की ढाल और (y)-अवरोध क्या हैं?
What are the slope and (y)-intercept of (9x-10y+30=0)?
Explanation opens after your attempt
A. ढाल \(\frac{9}{10}\), (y)-अवरोध (3)Slope \(\frac{9}{10}\), (y)-intercept (3)
Concept
From (-10y=-9x-30), \(y=\frac{9}{10}x+3\). So the slope is \(\frac{9}{10}\) and the (y)-intercept is (3).
Why this answer is correct
The correct answer is A. ढाल \(\frac{9}{10}\), (y)-अवरोध (3) / Slope \(\frac{9}{10}\), (y)-intercept (3). From (-10y=-9x-30), \(y=\frac{9}{10}x+3\). So the slope is \(\frac{9}{10}\) and the (y)-intercept is (3).
Exam Tip
(-10y=-9x-30) से \(y=\frac{9}{10}x+3\) मिलता है। इसलिए ढाल \(\frac{9}{10}\) और (y)-अवरोध (3) है।
