समीकरण (9y-7x=45) में (x=0) पर (y) का मान और ढाल क्या हैं?
In (9y-7x=45), what are the value of (y) at (x=0) and the slope?
Explanation opens after your attempt
A. (y=5), ढाल \(\frac{7}{9}\)(y=5), slope \(\frac{7}{9}\)
Concept
From (9y=7x+45), \(y=\frac{7}{9}x+5\). So at (x=0), (y=5) and the slope is \(\frac{7}{9}\).
Why this answer is correct
The correct answer is A. (y=5), ढाल \(\frac{7}{9}\) / (y=5), slope \(\frac{7}{9}\). From (9y=7x+45), \(y=\frac{7}{9}x+5\). So at (x=0), (y=5) and the slope is \(\frac{7}{9}\).
Exam Tip
(9y=7x+45) से \(y=\frac{7}{9}x+5\) मिलता है। इसलिए (x=0) पर (y=5) और ढाल \(\frac{7}{9}\) है।
