Answer:

Neither.

Step-by-step explanation:

You can only add exponents when multiple, or subtract when dividing.

Also, 2x^3 and 2x^2 are two different terms, not like terms, so cannot subtract the two.

1. Points M and N have coordinates (-4,0) and (4,2), respectively.

Then vector $\overrightarrow{MN}=(4-(-4),2-0)=(8,2)$ is perpendicular to the neede line.

2. Write the equation of line that passes through the point P(2,-4) and is perpendicular to vector $\overrightarrow{MN}=(8,2):$

$8(x-2)+2(y+4)=0,\\8x-16+2y+8=0,\\8x+2y-8=0,\\4x+y-4=0.$

3. Find the point on x-axis, that lies on the perpendicular line.

When y=0, then 4x-4=0, x=1 and point (1,0) lies on perpendicular line.

Answer: correct choice is C.
