Answer:

x = -2

(-2 , 4)

x = 0

(0 , 0)

x = 2

(2 , -4)

Step-by-step explanation:

y = -2x

we have to discover the value of y for when x is worth (-2, 0, 2)

so let's replace the x with each one and write your ordered pair

1) x = -2

y = -2x

y = -2(-2)

y = 4

( x , y)

(-2 , 4)

2) x = 0

y = -2x

y = -2(0)

y = 0

( x , y)

(0 , 0)

3) x = 2

y = -2x

y = -2(2)

y = -4

( x , y)

(2 , -4)

so we have that for each value of x we ​​have a different ordered pair
