Geo - Unit 4.5 HW - Slope

Front

What is the formula to calculate the slope between 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 that the line is vertical, meaning it goes straight up and down.

Front

How do you determine if a slope is positive, negative, or zero?

Back

A positive slope rises from left to right, a negative slope falls from left to right, and a zero slope is a horizontal line.

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 (5, 7), what is the slope?

Back

The slope is (7 - 3) / (5 - 2) = 4 / 3.

Front

If the slope between two points is -3, what does this indicate about the line?

Back

A slope of -3 indicates that the line falls steeply from left to right.

Front

What is the slope of the line represented by the equation y = 2x + 5?

Back

The slope of the line is 2.

Front

How do you find the slope between two points when one of the points has the same y-coordinate?

Back

If two points have the same y-coordinate, the slope is 0, indicating a horizontal line.

Front

What is the slope between the points (-1, 4) and (3, 4)?

Back

The slope is 0, as both points have the same y-coordinate.
