Slope (Table, Graph, Pattern)

Front

What is slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

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

Back

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

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, as there is no vertical change regardless of the horizontal change.

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined, as there is no horizontal change.

If a line has a slope of -3, what does this mean?

Back

This means that for every 1 unit increase in the x-direction, the y-value decreases by 3 units.

How can you identify the slope from a graph?

Back

The slope can be identified by selecting two points on the line, calculating the rise over run between them.

What is the slope of the line represented by the equation y = 4x + 2?

Back

The slope is 4, which is the coefficient of x in the equation.

If a pattern shows an increase of 2 tiles for every increase of 1 in the figure number, what is the slope?

Back

The slope is 2.
