Given:

In parallelogram ABCD, two of its vertices are A(-4,0) and B(0,3).

To find:

The equation that represents a line that contain CD.

Solution:

We have,

A(-4,0) and B(0,3)

Slope of AB is

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{3-0}{0-(-4)}

m=\dfrac{3}{4}

The slope of line AB is \dfrac{3}{4}.

Opposite sides of a parallelogram are parallel and slopes of parallel lines are equal.

In parallelogram ABCD, AB and CD are opposite sides. So, their slopes must be equal.

Slope of line AB = Slope of line CD = \dfrac{3}{4}

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

Slope of line CD is \dfrac{3}{4}, it means the line must be of the form

y=\dfrac{3}{4}x+b

Coefficient of x is \dfrac{3}{4} only in option a.

Therefore, the correct option is a.
