Finding Slope

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning it goes straight up and down.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

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

Back

A negative slope indicates that the line descends from left to right.

Front

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

Back

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

Front

Find the slope of the line that passes through the points (1, 2) and (3, 6).

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (0, 0) and (4, 8).

Back

The slope is 2.

Front

What is the slope of the line that passes through the points (2, 3) and (2, 5)?

Back

The slope is undefined.

Front

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

Back

The slope is 0.

Front

How do you determine if two lines are parallel based on their slopes?

Back

Two lines are parallel if they have the same slope.
