Y= 0.5x + 2 showing on the graph

Y is output, x is input

Step-by-step explanation:

I. Given x is -1, 0, 1

II. Perform x in linear equation

           If x is -1

             y = 0.5(-1) + 2

             y = 1.5  

            => (-1, 1.5) -1 is x, 1.5 is y

            If x is 0

               y = 0.5(0) + 2

               y = 2

              => (0, 2) 0 is x, 2 is y

            If x is 1

                y = 0.5(1) + 2

                y = 2.5

               => (1, 2.5) 1 is x, 2.5 is y

III. Perform (x, y) in graph, there will be something like this
