Question 1189162
Rick combines 8 atoms of hydrogen and 4 atoms of oxygen to make 4 molecules of water. Write a direct variation equation that relates atoms of oxygen O to atoms of hydrogen H. 
---
O = H/2
========================
How many hydrogen atoms does Rick need to form water molecules using 32 oxygen atoms? 
---
O = 2H ---> 64
----
Graph the variation with hydrogen along the x-axis.
