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.
