Graphing Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (x, y).

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on a graph.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on a graph.

Front

How do you plot the point (3, 4) on a graph?

Back

Start at the origin (0, 0), move 3 units to the right (x-axis), and then move 4 units up (y-axis).

Front

What is the difference between an equation and an expression?

Back

Equations have equal signs and expressions do not.

Front

Where is point E located if its coordinates are (0, 2)?

Back

Point E is located 2 units up on the y-axis.

Front

Which ordered pair matches the graph if the point is in the third quadrant?

Back

An example of an ordered pair in the third quadrant is (-1.25, -1.75).

Front

What does the symbol ≤ mean?

Back

The symbol ≤ means 'less than or equal to'.

Front

If you receive a score of 45 out of 50 on your test, how do you calculate your percent correct?

Back

Divide 45 by 50 and multiply by 100 to get 90%.

Front

What is the purpose of a coordinate plane?

Back

A coordinate plane is used to graph ordered pairs and visualize relationships between variables.
