Step-by-step explanation:
Given:
From the graph shown,
The broken line means that the inequality sign will be either < or >.
The shaded region is to the left of the broken line. This means that .
Now, in order to find equation of line, we need slope and y-intercept.
From the graph, the y intercept is at . So, y intercept is 1.
Also, if we consider two points on the line, then slope is given as:
Therefore, the equation of the line is given as:
But as the shaded region is to the left of the line,
∴ is the correct answer.
