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 first number in an ordered pair represent?

Back

The first number (x) represents the horizontal position on the graph.

Front

What does the second number in an ordered pair represent?

Back

The second number (y) represents the vertical position on the graph.

Front

How do you determine if an ordered pair is a solution to an equation?

Back

Substitute the x value into the equation and see if the resulting y value matches the y in the ordered pair.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation y = 2x - 4?

Back

The slope (m) is 2.

Front

What is the y-intercept of the line represented by the equation y = 2x - 4?

Back

The y-intercept (b) is -4.

Front

If x = 1, what is the value of y in the equation y = 2x - 2?

Back

y = 0.

Front

If x = 2, what is the value of y in the equation y = 2x - 2?

Back

y = 2.

Front

If x = 3, what is the value of y in the equation y = 2x - 2?

Back

y = 4.
