Slope & Rate of Change

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is always Zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is always Undefined.

Front

How do you 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 a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

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

Back

The slope of the line is 3.

Front

If a line has a slope of 0, what does that tell you about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that tell you about the line?

Back

An undefined slope indicates that the line is vertical.

Front

What is the slope of the line that passes through the points (1, 2) and (4, 5)?

Back

The slope is (5 - 2) / (4 - 1) = 3/3 = 1.

Front

What is the slope of the line represented by the equation y = -2x + 4?

Back

The slope of the line is -2.
