Finding Slope with 2 points

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

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

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 an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How do you find the slope of a line given two points with the same y-coordinate?

Back

If two points have the same y-coordinate, the slope is 0, indicating a horizontal line.

Front

How do you find the slope of a line given two points with the same x-coordinate?

Back

If two points have the same x-coordinate, the slope is undefined, indicating a vertical line.

Front

What is the slope of the line that passes through the points (2, 3) and (4, 7)?

Back

The slope is 2, calculated as (7 - 3) / (4 - 2).

Front

What is the slope of the line that passes through the points (1, 2) and (1, 5)?

Back

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

Front

If a line has a slope of -1/2, what does that indicate about the line's direction?

Back

A slope of -1/2 indicates that the line falls from left to right.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope of a perfectly vertical line is undefined.
