Please look in your text book for this problem Statement

Observe the graph:

Consider graph on the scale about and axis is .

Let the line passes through the points are and .

Find the slope.

.

                         (Formula for slope)

                       (Substitute and )

                                (Multiply)

                                      (Substitute: and )

                                      (Simplify)

Therefore, the slope is .

The slope is and the point is .

Slope-intercept form of the equation of a line is .

Find the slope intercept line equation.

                        (Slope-intercept form)

                     (Substitute and )

Therefore, the slpoe intercept form of the line eqaution is .

The line equation shaded region of the graph is shown as left of the -axis.

Therefore, the inequality is greater then be equal to left side shaded is .

Option D is right choice.
