Answer:
detail shown in step by step below
Step-by-step explanation:
y = mx + b m: slope b: y intercept
m = (y'-y) / (x'-x)
(28) (0,2) (3,0) m= -2/3 y < -2/3 * x +2
(0,-3) (3,0) m= 1 y > x - 3
(29) (-2,0) (-3,-2) m= 2 y < 2x + 4
(-4,-1) (0,-2) m= - 1/4 y ≥ (- 1/4) * x -2
(30) (0,3) (3,0) m= -1 y > - x + 3
(0,0) (1,3) m= 3 y ≥ 3x
(31) (0,4) (4,0) m= -1 y ≤ - x + 4
(3,3) (2,-1) m= 4 y ≥ 4x - 9
while x < 2
