Answer:
Step-by-step explanation:
When looking for constant rate, you have to see what is the repeating rate or coordinate in order to solve constant rate.
Let us take two coordinate points,
- ( 1 , 5 )
- ( 3 , 15 )
If we were to look for constant rate, we have to see the similarity (in this case the multiplication of the two numbers) between the two points.
What can they be?
They both have x multiplying by 5 to get y!
1 * 5 = 5
3 * 5 = 15
The same goes with all other points on the graph, leaving you with five as the constant rate.
