Finding Slope

Front

What is the formula to find the slope of a line?

Back

Slope (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 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

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

Back

A slope of 1 means that for every unit increase in x, y increases by the same amount.

Front

How do you determine the steepness of a line?

Back

The steepness of a line is determined by the absolute value of its slope.

Front

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

Back

The slope is 3.

Front

If a line has a slope of -2, what does this indicate about its direction?

Back

It indicates that the line descends steeply from left to right.

Front

What is the slope of the line represented by the equation y = -1/2x + 4?

Back

The slope is -1/2.
