Intro programming question:

Declare Real z = 9.2 Module main( ) Declare Integer x = 1 Declare Real y = 3.4 Declare Real z = 2.3 call change (x, y) Display x, " ", y End Module Module change(Integer Ref a, Real Ref b) Set a = 5 Set b = -1.5 Display a, " ", b End Module

As a result of calling the change( ) method and executing it, the value of the variable y will be ____ and the value of the variable x will be ___.

Would someone mind walking me through this? Thanks so much!
