Finding slope given 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

Calculate the slope of the line through the points (2, 3) and (5, 3).

Back

0

Front

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

Back

Undefined

Front

What is the slope of the line that passes through the points (0, 0) and (4, 4)?

Back

1

Front

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

Back

The line descends from left to right.

Front

Find the slope of the line through the points (-1, -1) and (2, 2).

Front

What is the slope of the line that passes through the points (3, 4) and (3, 1)?

Back

Undefined

Front

If the slope of a line is positive, what can be said about the line's direction?

Back

The line ascends from left to right.
