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).

How do you write the equation of a line in slope-intercept form?

Back

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

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and does not rise or fall.

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

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

Back

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

What is the equation of a line with a slope of 1 and a y-intercept of 2?

Back

The equation is y = 1x + 2 or simply y = x + 2.

Front

How do you convert a slope-intercept equation to standard form?

Back

To convert to standard form (Ax + By = C), rearrange the equation to get x and y on the same side.

Front

What is the significance of the slope in real-world contexts?

Back

The slope can represent rates of change, such as speed, growth, or decline in various real-world scenarios.
