Step-by-step explanation:
1. Distribute the X across the equation: 
2.
3.
3.
(20:4)x3=15 (Ellas grade)
(20:5)x4=16 (Minhs grade)
Total cost = 1.50 per bottle
y = 1.50x
If x = 1, y = $ 1.50 (1,1.5)
If x = 2, y = $ 3.00 (2,3)
If x = 3, y = $ 4.50 (3, 4.5)
If x = 4, y = $ 6.00 (4, 6)
There are your 4 sets of ordered pairs to graph.
You could continue with more x-values to get more ordered pairs.
