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. It is calculated as the ratio of the rise (change in y) over the run (change in x).

Front

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

Back

The slope (m) can be calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal, meaning there is no vertical change as you move along the line.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as you move from left to right along the line, the y-values increase.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as you move from left to right along the line, the y-values decrease.

Front

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

Back

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

Front

How do you find the x-intercept of a line given its equation?

Back

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

Front

Back

The x-intercept is 40.

Front

What is the equation of a line with a zero slope that passes through the point (6, 7)?

Back

The equation is y = 7.

Front

What is a linear equation?

Back

A linear equation is an equation that represents a straight line when graphed. It can be written in the form Ax + By = C.
