Test Nov 21 on Slope

Front

What is the formula to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is 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.

Front

What does a positive slope indicate about the direction of a line?

Back

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

Front

What does a negative slope indicate about the direction of a line?

Back

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

Front

How do you find the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If the coordinates of two points are (3, 2) and (3, 5), what is the slope of the line through these points?

Back

The slope is undefined because the x-coordinates are the same.

Front

What is the slope of a line that runs parallel to the x-axis?

Back

The slope of a line parallel to the x-axis is 0.

Front

What is the slope of a line that runs parallel to the y-axis?

Back

The slope of a line parallel to the y-axis is undefined.

Front

Given the points (1, 2) and (4, 8), calculate the slope of the line through these points.

Back

The slope is 2, calculated as (8 - 2) / (4 - 1).

Front

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

Back

The slope represents the rate of change between two variables in real-world contexts.
