Explanation:
To graph 11) The vertex is (0, -4) because the y-intercept is -4.
The slope is 1/2 so draw the line according to the picture above.
Since the inequality does not have or equal to, the line is broken instead of solid.
Since the inequality is greater than, the shaded area should be above the line.
To graph 12) The vertex is (3, 0) because the x-intercept, or the number inside the absolute value signs, is -3. Negative is right, positive is left.
The slope is -1, so draw the "v" upside down and according to the second picture above.
Since the inequality does not have or equal to, the line is broken.
Since the inequality is less than, the shaded area is below the line.
