Arectangle on a coordinate plane has vertices l(0, 6), m(8, 6), n(8, 0), and o(0, 0). what are the dimensions of the rectangle? the base is 6 and the height is 8. the base is 8 and the height is 6. the base is 6 and the height is 6. the base is 8 and the height is 8.

The answer would be what I assume to be B) The base is 8 and the height is 6.

(I graphed the rectangle for visual representation.)

Even without the graph, you could just look at this problem and do a little mental math.  With the L coordinate, it's telling you that the height is 6 because it is being graphed along the y-axis.  With the N coordinate, it's telling you that the base is 8 because it is being graphed along the x-axis.  It also helps that the x- and y-coordinates of L and N are 0; it makes the mental part much easier.
