Explanation opens after your attempt
D. (14)
Concept
The slope is (k-5) and (8(k-5)=72). Therefore (k-5=9) and (k=14).
Why this answer is correct
The correct answer is D. (14). The slope is (k-5) and (8(k-5)=72). Therefore (k-5=9) and (k=14).
Exam Tip
ढाल (k-5) है और (8(k-5)=72)। इसलिए (k-5=9) और (k=14) है।
