Cirrus clouds form at a height of more than 6000 meters above the earth. This means the inequality should represent the height more than 6000. The correct inequality for this case will be:

This inequality shows that h which is height where Cirrus clouds are formed is greater than 6000m.
The third fin is the answer.
Answer:
green: y= 1x+4
yellow: undefined x=1
blue: y= 2/-1x + 4
black: y= 0+-6
Step-by-step explanation:
ausuming u need slope intercept form
Take -920/360 = -2.55555
Take the fraction part -0.5555555 * 360 = -200
The positive of that would be 160 degrees
