Question 43/50 Medium Mathematics Introduction to Polynomials Slope and y-intercept Class 9 Level 39

कौन सी रेखा (x=0) पर (y=-8) देती है और ढाल (6) रखती है?

Which line gives (y=-8) at (x=0) and has slope (6)?

Explanation opens after your attempt
Correct Answer

A. (y=6x-8)

Explanation

Simple Explanation

(x=0) पर (y=-8) का अर्थ (c=-8) है। ढाल (6) से रेखा (y=6x-8) है। / (y=-8) at (x=0) means (c=-8). With slope (6), the line is (y=6x-8).

रेखा (y=9x+2) और (y=-9x+2) के बारे में सही कथन क्या है?

Which statement about (y=9x+2) and (y=-9x+2) is correct?

Explanation opens after your attempt
Correct Answer

B. ढाल अलग है और (y)-अवरोध समान हैंSlopes are different and (y)-intercepts are same

Explanation

Simple Explanation

ढालें (9) और (-9) हैं लेकिन स्थिर पद (2) समान है। इसलिए (y)-अवरोध समान हैं। / The slopes are (9) and (-9), but the constant term (2) is the same. So the (y)-intercepts are the same.
