Which of the following is an example of an ordered pair?

(2,9) An ordered pair is defined as a set of coordinates shown as two numbers inside parentheses.

What are the coordinates of this point?

(-3, 4) Ordered pairs always follow the (x,y) format. The point is located -3 on the x-axis and 4 on the y-axis.

What is the special name for the coordinate (0,0)?

Origin The point at the very middle of the graph is called the origin, and its coordinates are (0, 0), because it's 0 units away from the center of the graph in both directions.

Which graph has a positive x-intercept and a negative y-intercept?

The line crosses the x-axis to the right of the origin, making it positive, and it crosses the y-axis beneath the origin, making it negative.

The point (1, -5) would be found where on the Cartesian plane?

In the lower-right quadrant On the Cartesian plane, Quadrant 4 has the x value positive and the y value negative.
