Front

What is the formula for calculating slope?

Back

Slope = Rise / Run

Front

Front

If a line rises as it moves from left to right, what is the slope?

Back

The slope is positive.

Front

If a line falls as it moves from left to right, what is the slope?

Back

The slope is negative.

Front

What is the slope of a horizontal line?

Back

The slope is 0.

Front

What is the slope of a vertical line?

Back

The slope is undefined.

Front

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

Back

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

Front

What is the slope of the line that passes through the points (2, 3) and (5, 7)?

Back

Slope = (7 - 3) / (5 - 2) = 4/3.

Front

What is the slope of the line that passes through the points (1, 2) and (1, 5)?

Back

The slope is undefined.
