The linear equality represented by the graphis and it matches with .
Further explanation:
From given graph, theline passes through points and as shown below in Figure 1.
The slope of a line passes through points and is calculated as follows:
......(1)
Here, the slope of a line is denoted as and points are and .
Substitute for , for , for and for in equation (1) to obtain the slope of a line that passes through points and .
Therefore, the slope is .
The point-slope form of the equation of a line with slope passes through point is represented as follows:
......(2)
Substitute for , for and for in equation (2) to obtain the equation of line.
Further simplify the above equation.
Therefore, the value of is .
Since the shaded part in Figure 1 is above the equation of line , therefore, greater than sign is used instead of is equal to
Therefore, the inequality is .
Now, the four options are given below.
Since OPTION C matches the obtained equation that is .
Thus, the linear equality represented by the graph is and it matches with
