Will give graph the ordered pairs for y = 2x + 4 using x={−2,  1, 2} . state what are the exact points.

Step-by-step explanation:

We have the equation,

y = 2x + 4.

The range for x is given by { -2, 1, 2 }.

We now substitute these values of x in y = 2x + 4 to obtain the corresponding values of y.

At x = -2, → → y = 0

At x = 1 , → → y = 6

At x = 2, → → y = 8

So, the range of y is { 0, 6, 8 }

Plotting the ordered pairs (-2,0) , (1,6) and (2,8)  gives the following graph.
