Answer: C) y ≥ 3x - 2; 
<u>Step-by-step explanation:</u>
Blue line:
y-intercept (b) = -2
slope (m) is 3 up, 1 right = 3
shading is above
⇒ y ≥ 3x - 2
Yellow line:
y-intercept (b) = 3
slope (m) is 1 up, 2 right = 
shading is below

Step-by-step explanation:
Area = 8 × 5
Area = 40^2
Perimeter is the length around the edges
Therefore it is 8+8+5×5 (since there are 4 edges)
Perimeter = 2×8 + 2×5
= 40 + 10
= 50cm
