Find the missing point- Slope

Front

What is the formula to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

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

Back

An undefined slope indicates a vertical line, where the x-coordinates of the two points are the same, resulting in division by zero.

Front

What is the slope of a line that rises from left to right?

Back

The slope is positive.

Front

What is the slope of a line that falls from left to right?

Back

The slope is negative.

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.

Front

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

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

Given the points (2, 3) and (4, 7), what is the slope of the line connecting them?

Back

The slope is 2, calculated as (7 - 3) / (4 - 2).

Front

If a line has a slope of -3, what does this indicate about the line's direction?

Back

The line falls from left to right.
