Intro to Linear Relationships

Front

How do you write an ordered pair?

Back

(x, y) - An ordered pair consists of two numbers, where 'x' is the first number (the x-coordinate) and 'y' is the second number (the y-coordinate).

The y-axis is _______?

Back

Vertical - The y-axis is the vertical line on a graph that represents the values of the dependent variable.

Front

What does the x-axis represent in a graph?

Back

The x-axis represents the horizontal line on a graph that typically shows the independent variable.

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if a line has a positive slope?

Back

A positive slope means that as the x-value increases, the y-value also increases.

Front

What does it mean if a line has a negative slope?

Back

A negative slope means that as the x-value increases, the y-value decreases.

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis, represented as (x, 0).
