Which option makes (y) decrease by (13) per step and has (y(6)=71)?
Explanation opens after your attempt
B. (y=149-13x)
Concept
The rate is (-13), and (a-13(6)=71) gives (a=149). So (y=149-13x) is correct.
Why this answer is correct
The correct answer is B. (y=149-13x). The rate is (-13), and (a-13(6)=71) gives (a=149). So (y=149-13x) is correct.
Exam Tip
दर (-13) है और (a-13(6)=71) से (a=149) मिलता है। इसलिए (y=149-13x) सही है।
