H) y = 3/10x

1) Examining the data y=21/2 when x= 35

2) A direct relationship implies multiplication and a linear function without linear coefficient y=mx.

Setting a Table

x | y

35 10.5

Then examine the relationship between those entries we have

dividing 35 /10.5 = 3/10

y=3/10x

3) Then the answer is H) y = 3/10x or y =0.3x
