Answers: All the options are right and have a special meaning.
Explanation:
1) <span>Δy = 0
Means y is constant, which is also that the slope is zero.
The function is a horizontal line (paralell to the x-axis)
2) Δx = 0
Means x is constant, the slope is not defined (∞).
The function is a vertical line (parallel to the y-axis)
3) Δy = n
Means that the change in y is constant. So, only if the change in x is also constant the slope is constant and the function is linear.
This is because the slope is Δy / Δx.
4) Δx = n
Means the change in x is constant. So, only if Δy is constant it is a linear function, for the same reason explained above
5) Δy = -n and and 6) Δx = -n
Same reasoning of 3 and 4.

Answer:
he has 20 chickens
Step-by-step explanation:
i was testing with it. 20 dog legs divided by 4 (since dogs have 4 legs) equals 5. 5 times 4 (since 4 times the amount of dogs) is 20. then to check, 20 times 2 (since chickens have 2 feet) is 40. 20 dog legs plus 40 chicken legs. makes sense. again, 20 chickens.
