Anon25 [30]

Answer:

Option (A)

Step-by-step explanation:

Plane is travelling at a constant speed = K miles per hour

K = $\frac{\text{Distance}}{\text{Time}}$

Distance = k(Time)

For Time of traveling = 1 hour

Distance traveled = k × 1

= k miles

Therefore, k miles will be traveled in one 1 hour and ordered pairs of the given point on the line will be (1, k)

Option (A) will be the correct option.
