Question

Write the inequality shown by the shaded region in the graph with the boundary line 3x-y=9.

Answer 1

The equation given is,

`3x-y=9`

Since the boundary line is thick bold line and from the graph we can observe that the line (shaded portion) moves from the right to the left hand side.

Then the inequality of the shaded region is,

`3x-y\leq9`
