The question provides us with a graph and we are required to know what system of inequalities describe the graph.

Before we decide whether or not an expression has greater or less than inequaity, let us assume they are normal lines.

We can decide what expression the line must be using the general slope-intercept form given below:


\begin{gathered} y=mx+c \\ \text{where,} \\ m=\text{slope} \\ c=y-\text{intercept (where the line crosses the y-axis)} \end{gathered}

In order to find the slope of a line, we use the following formula:


\begin{gathered} \text{given two points,} \\ (x_1,y_1),(x_2,y_2) \\ m=(y_2-y_1)/(x_2-x_1) \end{gathered}

With this information, we can find the slope and y-intercept o

Observing the graph, we can pick two easy
