What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the equation of a line (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

How do you find the slope from a graph?

Back

To find the slope from a graph, select two points on the line, determine the vertical change (rise) and the horizontal change (run) between these points, and then divide the rise by the run.

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship between the two variables.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing an inverse relationship between the two variables.

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as 'b' in the equation of a line (y = mx + b).

Front

How do you identify the y-intercept from an equation?

Back

In the equation of a line in slope-intercept form (y = mx + b), the y-intercept is the constant term 'b'.

What is a rate of change?

Back

The rate of change is a ratio that describes how one quantity changes in relation to another quantity, often represented as the slope in a linear relationship.

How do you calculate the rate of change from a table?

Back

To calculate the rate of change from a table, find the difference in the y-values and divide it by the difference in the x-values for two points.

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

Back

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

What does the slope represent in a real-world context?

Back

In a real-world context, the slope can represent rates such as speed, cost per item, or any other ratio that describes how one quantity changes with respect to another.
