The sides of a triangle are 3 x+2 y-6=0,2 x-3 y+6=0 and x+2 y+2=0 . If P(0, b) lies either on the triangle or inside the triangle, then b lies in the interval
Options
- A[-1,3]
- B[2,3]
- C[-1,2]
- D[-2,2]
Correct answer
C. [-1,2]
Step-by-step solution
Given 3 x+2 y-6=0,2 x-3 y+6=0, x+2 y+2=0 We can re-write it as follows x 2 + y 3 =1, x (-3) + y 2 =1, x -2 + y -2 =1 P (0, b) The triangle A B C in the above graph is the required triangle. In which, clearly, (0, b) can vary from point (0,2) to (0,-1) . So, range of b is [-1,2] .
