Therefore, any point, indicated as (x, y), in the first quadrant will be positive at both x and y. Quadrant IV, in the lower right of the graph, contains only points that are to the right of zero on the x-axis and below zero on the y-axis; therefore, all points in this quadrant will have a positive x value and a negative y value. Kim has a Ph.D. in Education and has taught math courses at four colleges, in addition to teaching math to K-12 students in a variety of settings.
