Slope from two points

Front

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

Back

m = (y2 - y1) / (x2 - x1)

Front

What does it mean if the slope of a line is undefined?

Back

The line is vertical, meaning it goes straight up and down.

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of a horizontal line?

Back

0

Front

How do you determine if two points have the same x-coordinate?

Back

If the points are of the form (x, y1) and (x, y2), they have the same x-coordinate.
