Solve for the line on the graph by finding the slope and the y intercept.

Slope = change in y over change in x.

Using the two blue dots (-1,-3) and (0,-5)

Slope = (-5 - -3) / (0- -1) = -2/1 = -2

Y intercept is the y value when x is 0 which is -5

The equation of the line is y = -2x-5

Now the colored area is the the right of the line and the line is a solid line. This means y is greater than or equal to the equation.

The answer is y >= ( greater than or equal to) -2x-5
