Correct Answer

C. (8)

Step 1

Concept

The slope is (k+7) and (5(k+7)=75). Therefore (k+7=15) and (k=8).

Step 2

Why this answer is correct

The correct answer is C. (8). The slope is (k+7) and (5(k+7)=75). Therefore (k+7=15) and (k=8).

Step 3

Exam Tip

ढाल (k+7) है और (5(k+7)=75)। इसलिए (k+7=15) और (k=8) है।
