How can Nassir show the slope is constant and show what the constant slope represents in this situation? Drag and drop the correct option into each box to answer the question.

Nassir can draw vertical segments from any two points on the line to the ​ (a)   to form ​ (b)   triangles. This will show that the ​ (c)   change divided by the ​ (d)   change for any point on the line is the same, so the slope is constant. The constant slope represents the amount of water collected is the same ​ (e)   the watering can is filled.
