5.4C Math Ordered PAirs

Front

What is an ordered pair?

Back

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

Front

What does the x-axis represent in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0, 0).

Front

How do you find the y-coordinate using the equation y = x + 4.1?

Back

To find the y-coordinate, substitute the value of x into the equation and solve for y.

Front

What is the slope of the line represented by the equation y = 5x?

Back

The slope of the line is 5, which means for every 1 unit increase in x, y increases by 5 units.

Front

What is a function in mathematics?

Back

A function is a relation where each input (x) has exactly one output (y).

Front

What does it mean for points to satisfy an equation?

Back

Points satisfy an equation if their coordinates make the equation true when substituted into it.

Front

What is a table of values in relation to a function?

Back

A table of values lists pairs of x and y coordinates that satisfy a function.

Front

How can you graph an equation like y = x + 2.5?

Back

To graph the equation, plot points using ordered pairs from a table of values and connect them to form a line.
