Answer:

d. (2, 0)

Step-by-step explanation:

Parallel lines have the same slope.

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points A(-4, 0) and B(2, -3). Substitute:

[tex]m=\dfrac{-3-0}{2-(-4)}=\dfrac{-3}{6}=-\dfrac{1}{2}[/tex]

C(-2, 2).

The point on the x-axis D(x , 0).

The slope:

[tex]m=\dfrac{0-2}{x-(-2)}=\dfrac{-2}{x+2}[/tex]

Put the value of the slope:

[tex]\dfrac{-2}{x+2}=\dfrac{-1}{2}[/tex]           change the signs

[tex]\dfrac{2}{x+2}=\dfrac{1}{2}[/tex]           cross multiply

[tex]x+2=(2)(2)[/tex]

[tex]x+2=4[/tex]            subtract 2 from both sides

[tex]x=2[/tex]
