Slope using 2 Ordered Pairs

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 is the slope of a horizontal line?

Back

The slope is 0.

Front

Calculate the slope of the line that passes through the points (2, 3) and (2, 7).

Back

undefined

Front

Calculate the slope of the line that passes through the points (1, 2) and (4, 5).

Back

1

Front

What is the slope of the line that passes through the points (0, 0) and (3, 3)?

Back

1

Front

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

Back

The line descends from left to right.

Front

Calculate the slope of the line that passes through the points (5, 2) and (10, 2).

Back

0

Front

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

Back

1

Front

If two points have the same x-coordinate, what can be said about the slope of the line connecting them?

Back

The slope is undefined.
