What is the definition of slope in mathematics?

Back

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

What is the formula for calculating 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 does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning it goes straight up and down and does not have a defined angle.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no vertical change as you move along the line.

How do you determine if a slope is positive or negative?

Back

A slope is positive if it rises from left to right and negative if it falls from left to right.

What is the significance of a slope of 1?

Back

A slope of 1 indicates that for every unit increase in the x-direction, there is an equal unit increase in the y-direction, resulting in a 45-degree angle.

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

Back

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

How can 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 horizontal change (run), and use the formula m = rise/run.
