Think of any point on the graph as a location with 2 coordinates; i.e., an x -coordinate (which can be read off the x - axis) and a y- coordinate (which can be read off the y -axis). See examples on next page… y 6 8 10 x 2 4 6 8 -8 -6 -4 -2 2 4 -8 -6 -4 -2 -10 -10 10

Consider these four points… (5, 5) (-3, -4) +5 +5 Notice: The first number (the number on the left) is always the x value and -3 -4 (-6, 2.5) (8, -7) +8 -7 the second number (the number on the right) is always the y value. -6 +2.5

Plotting Points on a Graph To plot a point such (7, 4) on a graph, we start at the origin and move along the x axis according to the x coordinate. Since the x coordinate is 7, we will move 7 units to the right; i.e., the positive x direction… Then we will move from our current position up or down, i.e., parallel to the y axis according to the y coordinate of the point we are trying to graph.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
