Finding Slope from Graph and Two Points

Front

What is the formula to find 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 is the slope of a horizontal line?

Back

The slope is 0.

Front

Find the slope of the points (1, 2) and (3, 2).

Back

0

Front

Find the slope of the points (2, 3) and (2, 5).

Back

undefined

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

Find the slope of the points (4, 1) and (6, 5).

Back

1

Front

If the slope of a line is -3, what does this tell you about the line's direction?

Back

The line falls as it moves from left to right.
