Question

1. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
x Y
52 39
32 24
20 15
8 6

Answer 1

please explain it

Answer 2

The first thing I'd do here would be to determine whether y increases as x increases, or whether y decreases when x increases.

This table is written upside down, probably to make the problem more challenging to the unwary!

But take a look at the table: If x increases, does y increase or decrease?

Answer 3

ok thansk

Answer 4

well if it was negative then why would decrease but a posative should increase
