1) For the data in the table, does y vary directly with x? If it does, write an equation for the direct
variation.

Answer:
Yes, y varies directly with x.
[tex]y=\frac{11}{8} x[/tex]
Step-by-step explanation:
[tex]\frac{y}{x}=\frac{11}{8} =\frac{22}{16} =\frac{33}{24}[/tex]
Hence [tex]y[/tex] varies directly with [tex]x[/tex].
[tex]\frac{y}{x}=\frac{11}{8} \\\\ y=\frac{11}{8} x[/tex]
