Front

What does the equation y = x + 3 represent?

Back

It represents a linear relationship where for every increase of 1 in x, y increases by 1, starting from 3.

Front

What is an ordered pair in a graph?

Back

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

Front

What does the x-value represent in an ordered pair (x, y)?

Back

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

Front

What does the y-value represent in an ordered pair (x, y)?

Back

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

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope in a linear equation represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x is 0, represented by b in the equation.

Front

How do you determine if a relationship is additive?

Back

A relationship is additive if each y-value can be found by adding a constant to the corresponding x-value.

Front

What is a multiplicative pattern?

Back

A multiplicative pattern occurs when each y-value is a multiple of a corresponding x-value.

Front

What does the equation y = 3x mean?

Back

It means that for every 1 unit increase in x, y increases by 3 units.
