The line is a dashed line, it means that the line is not included in the solution and the equation must have the symbol > or < not ≥ or ≤.
By looking at the graph we can see that the line crosses the y-axis at y=4.
Slope intercept equation:
y= mx +b
Where :
m= slope
b= intercept (4)
To find the slope we can see that moving from left to right, the line goes down 2 units (-2) for every unit to the right.
m= rise / run = -2/1 = -2
Final equation:
y> -2x+4
the solution is above the line, so y it's greater than the line.
