Answer:

Option (a)

Step-by-step explanation:

Slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

Slope (m) = \frac{y_2-y_1}{x_2-x_1}

Slope of the line passing through (-4, 3) and (6, 3) will be,

m = \frac{3-3}{6+4}

m = 0

In other words, slope of any line parallel to x-axis is zero.

Therefore, Option (a) is the answer.
