Correct Answer

C. (18)

Step 1

Concept

From (9y=-bx+54), the slope is \(-\frac{b}{9}\). From \(-\frac{b}{9}=-2\), (b=18).

Step 2

Why this answer is correct

The correct answer is C. (18). From (9y=-bx+54), the slope is \(-\frac{b}{9}\). From \(-\frac{b}{9}=-2\), (b=18).

Step 3

Exam Tip

(9y=-bx+54) से ढाल \(-\frac{b}{9}\) है। \(-\frac{b}{9}=-2\) से (b=18) है।
