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 graph?

Back

The x-axis is the horizontal line in a graph that represents the input values (or independent variable).

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line in a graph that represents the output values (or dependent variable).

Front

What is the equation of a line that has a slope of 1 and a y-intercept of 2.5?

Back

The equation is y = x + 2.5.

Front

What is a multiplicative pattern?

Back

A multiplicative pattern is a relationship where one quantity is multiplied by a constant to get another quantity, often represented as y = kx.

Front

What is an additive pattern?

Back

An additive pattern is a relationship where a constant is added to a quantity to get another quantity, often represented as y = x + b.

Front

How do you find the output value using the equation y = 3x for x = 2?

Back

Substitute x with 2: y = 3(2) = 6.

Front

What is the purpose of an input-output table?

Back

An input-output table is used to organize pairs of input values (x) and their corresponding output values (y) based on a specific rule or equation.

Front

What does the term 'slope' refer to in a graph?

Back

The slope refers to the steepness of a line on a graph, indicating how much y changes for a change in x.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.
