Slope from a Graph

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as you move from left to right, the line rises.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as you move from left to right, the line falls.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

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

Back

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

Front

If a line has a slope of 0, what type of line is it?

Back

A line with a slope of 0 is a horizontal line.

Front

If a line has a slope of 1, what does that mean?

Back

A slope of 1 means that for every unit you move right, you move up one unit.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope of the line is 2.

Front

What is the slope of the line represented by the equation y = -3x + 1?

Back

The slope of the line is -3.

Front

What is the slope of the line represented by the equation y = 0?

Back

The slope of the line is 0 (horizontal line).
