Question

I’m so confused pls help

Answer 1

First, third, fourth

Explanation:

For first equation,

a = b²

Here a = b*b

Hence, we can say there's a direct relationship between a and b.

For second equation,

a = 2/b

Here b is on the denominator.

Considering 2 as a constant,

a is indirectly proportional to b.

For third equation,

a = 2b

Considering 2 to be constant,

a is directly proportional to b.

For fourth equation,

a = b/2

Considering 2 to be constant,

a is directly proportional to b.

For fifth equation,

a = b+2

Here there is not direct (indirect) relationship between a and b since there's no clear relationship in terms of "*" and "÷".
