Represent to solution set of each of the following inequations graphically in two dimensional plane:
y ≥ 2x − 8
उत्तर
Converting the inequation to equation, we obtain 2x \[-\] y\[-\]8 =0
Putting y = 0 and x = 0 in this equation, we obtain x = 4 and y = \[-\]8 respectively.
So, this line meets the x-axis at (4,0) and y-axis at (0,\[-\]8).
We plot these points and join them by a thick line.This divides the xy plane into two parts.
To determine the region represented by the given inequality, consider point O(0,0).
Clearly, (0,0) does satisfy the inequality.
So, the region containing the origin is represented by the given inequality.
Hence, the shaded region is the solution to the inequation.
