कौन सी रेखा ( (0,-11) ) पर (y)-अक्ष काटती है और (x) के (5) बढ़ने पर (y) (40) बढ़ाती है?
Which line cuts the (y)-axis at ( (0,-11) ) and increases (y) by (40) when (x) increases by (5)?
Explanation opens after your attempt
A. (y=8x-11)
Concept
The slope is \(\frac{40}{5}=8\) and the (y)-intercept is (-11). So the line is (y=8x-11).
Why this answer is correct
The correct answer is A. (y=8x-11). The slope is \(\frac{40}{5}=8\) and the (y)-intercept is (-11). So the line is (y=8x-11).
Exam Tip
ढाल \(\frac{40}{5}=8\) है और (y)-अवरोध (-11) है। इसलिए रेखा (y=8x-11) है।
