कौन सी रेखा ((0,-16)) पर (y)-अक्ष काटती है और (x) के (7) बढ़ने पर (y) (70) बढ़ाती है?
Which line cuts the (y)-axis at ((0,-16)) and increases (y) by (70) when (x) increases by (7)?
Explanation opens after your attempt
A. (y=10x-16)
Concept
The slope is \(\frac{70}{7}=10\) and the (y)-intercept is (-16). So the line is (y=10x-16).
Why this answer is correct
The correct answer is A. (y=10x-16). The slope is \(\frac{70}{7}=10\) and the (y)-intercept is (-16). So the line is (y=10x-16).
Exam Tip
ढाल \(\frac{70}{7}=10\) है और (y)-अवरोध (-16) है। इसलिए रेखा (y=10x-16) है।
