The graph of the inequality is the shaded region and boundary of the inequality is
. To graph the boundary, find the x-intercept and y-intercept of the line.
First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\ (Substitute x = 0 in original equation)
(Apply Additive identity property: 0 – 6y = – 6y)
Apply subtraction property of equality: If a = b than a – c = b – c.
\ (Subtract 3 from each side)
(Apply Additive inverse property: 3 – 3 = 0)
Apply division property of equality: If a = b than .
(Divide each sige by negative 6)
(Cancel common terms)
(Divide:
)
The y-intercept is 0.5, so the graph intersects the y-axis at (0, 0.5).
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\ (Substitute y = 0 in original equation)
(Apply zero product property:
)
(Subtract 3 from each side)
(Apply Additive inverse property: 3 – 3 = 0)
The x-intercept is – 3 , so the graph intersects the x-axis at ( – 3, 0).
To draw inequality follow the steps.
1. Draw a coordinate plane.
\2. Plot the points.
\3. Since inequality symbol is >, the boundary is not included in the solution set. Graph the boundary of the inequality
with a dashed line.
4. To determine which half-plane to be shaded use a test point in either half-plane. A simple choice is (0, 0).
\Substitute and y = 0 in original inequality .
The statement is true.
\5. Since the statement is true, shade the region that contains point (0, 0).
