    Look at the diagram and focus on the point where the two lines intersect.

    I think so but I need to look again. Is the y-value -3 or -4 ?

    I counted that this time. I have "allery eyes." The point with c(o,o)rdinates (4, -3) is called the simultaneous solution of the two linear equations because that point makes both equations true at the same time. Note that the point is located in the fourth quadrant.

    Clarification: By "allergy eyes," I mean the pollen where I live is heavy and has irritated my eyes.
