URGENT!!! Slope of a Trapezoid

[honeybreeze]

This is a question regarding geometry. There is a trapezoid, sides ABCD. The question states that AB's slope is 3/4, and asks, "What is the slope of CD?". Please give me the answer if you know it ASAP.

What is the definition of a trapezoid?

This is a question regarding geometry. There is a trapezoid, sides ABCD. The question states that AB's slope is 3/4, and asks, "What is the slope of CD?". Please give me the answer if you know it ASAP.

You have to assume something from the picture that is not explicitly stated, namely which sides are the bases. Assuming, as in the picture, that the bases are AB and CD, what do you know about them? What does that imply about their slopes?

Note that it is not the sides that are ABCD, but the vertices.
