Question

PLEASE HELP!! Will give brainliest!!

Answer 1

2(-2) + 4 = 0 meaning the point would go on -2,0
2(1) + 4 = 6 meaning the point would go on 1,6
2(2) + 4 = 8 meaning the point would go on 2,8
so ur points are
-2,0
1,6
2,8

hoped that helped

Answer 2

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, $y = 2 \times (-2) + 4$ → $y = -4 + 4$ → y = 0

At x = 1 , $y = 2 \times (1) + 4$ → $y = 2 + 4$ → y = 6

At x = 2, $y = 2 \times (2) + 4$ → $y = 4 + 4$ → 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.
