Answer:

3

Step-by-step explanation:

Since there is no increase in height, we will look at the horizontal distance.

We can compare the distance from (0,0) to (5,0) and (15,0)

Distance from (0,0) to (5,0) = 5 units

(0,0) to (15,0) = 15 units

So, k is the ratio of the new distance over the original: k = 15/5 --> k = 3
