The direct linear variation equation is: ( y = kx ), where ( k ) is the constant of variation.
Given that ( y = 0.8 ) when ( x = 0.5 ), we can substitute these values into the equation to find the value of ( k ):
( 0.8 = k \times 0.5 )
Solving for ( k ):
( k = \frac{0.8}{0.5} = 1.6 )
So, the direct linear variation equation is: ( y = 1.6x ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
