Answer
Explanation:
Step1: Recall the definition of cotangent
For a point ((x,y)) on the terminal arm of an angle, (\cot\theta=\frac{x}{y}). Here (x = 2) and (y=-3).
Step2: Calculate (\cot B)
Substitute (x = 2) and (y =-3) into the formula (\cot B=\frac{x}{y}), we get (\cot B=\frac{2}{-3}=-\frac{2}{3}).
Answer:
D. (-\frac{2}{3})
