Slope Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the rise (vertical change) to the run (horizontal change).

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept of a line?

Back

To find the y-intercept, set x = 0 in the equation of the line and solve for y.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis, found by setting y = 0 in the equation.

Front

How do you convert the equation 3x + y = 12 to slope-intercept form?

Back

Rearranging gives y = -3x + 12.

Front

What is the rise in the slope formula?

Back

The rise is the vertical change between two points on a line.

Front

What is the run in the slope formula?

Back

The run is the horizontal change between two points on a line.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal.
