Question

Choose the correct set of y-values for the function y = -2x when x = -2, 0, 2. (-2, -4), (0, 0), (2, -4) (-2, 4), (0, -2), (2, 4) (-2, 4), (0, 0), (2, -4) (-2, -4), (0, 0), (2, 4)

Answer 1

x = -2

(-2 , 4)

x = 0

(0 , 0)

x = 2

(2 , -4)

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

Answer 2

(-2,4), (0,0),(2,-4)

Explanation:

y = -2x

If x=-2, then y=-2*(-2)=4....... (-2,4)

if x=0, then y=-2*0=0............(0,0)

if x=2, then y=-2*2=-4...........(2,-4)
