Answer:
The answer depends on x.value
Step-by-step explanation:
I. It's linear equation
           y = mx + b
when y is output, x is input, m is slope and b is addition
    So if x = -1
           y = -4/3(-1) - 2
              = 4/3 - 2
              = (4-6)/3
            y = -2/3
    It will be something like this (-1, -2/3) when -1 is x.value, -2/3 is y.value         
You can given x.value be anything like 0, 1, 2, 3 the graph will be like this
