Y is the second number in a set of ordered pairs.
If you are talking about the things in the perentheses, (5,-9), they are called ordered pairs. Ordered pairs help you find a location on a coordinate graph.
Y2-y1 x2-x1
y=3x-5
I assume the ordered pairs are connected by straight lines. You can draw the corresponding figure (this helps you visualize it), then divide it into rectangles and triangles, calculate each partial area, and add everything up.
