Given:

The graph of an inequality.

To find:

The inequality in slope intercept form.

Solution:

The slope intercept form is:


y=mx+b

Where, m is slope and b is y-intercept.

From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).


y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)


y-0=(-3-0)/(0-(-3))(x-(-3))


y=(-3)/(3)(x+3)


y=-1(x+3)


y=-x-3

From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".


y\geq -x-3

Therefore, the required inequality is
y\geq -x-3.
