Slope Flashcard

Front

What is the slope?

Back

The slope is a measure of the steepness or incline of a line, calculated as the change in vertical distance divided by the change in horizontal distance.

Front

What type of slope is represented by a horizontal line?

Back

A horizontal line has a slope of zero.

Front

What type of slope is represented by a vertical line?

Back

A vertical line has an undefined slope.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

If the slope is negative, what does it indicate about the line?

Back

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

Front

If the slope is positive, what does it indicate about the line?

Back

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

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.

Front

What is the slope of the line that passes through the points (2, 5) and (2, 10)?

Back

The slope is undefined.

Front

If a skier descends at a rate of 25 feet every five seconds, what is the slope of their descent?

Back

The slope is 5 feet per second.

Front

If a line has a slope of 0, what does that mean about the y-values?

Back

The y-values remain constant regardless of the x-values.
