Question

find several solutions of the equation y= 3x - 2. Explain how these solutions are related to input- output pairs for y = 3x - 2.

Answer 1

y=0 , x= 3/2....x=0, y= -2...

Answer 2

The given function has infinite number of solutions

let x = 0

y = -2

let x = 1

y = 3 -2 = 1

x is the independent variable and can take any value while y the dependent variable gets its value out of the function.
