Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the slope of a horizontal line?

Back

0

Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of the line represented by the equation y = mx + b?

Back

The slope is m.

Front

If a line has a slope of 4/3, what does this mean in terms of rise over run?

Back

For every 4 units the line rises, it runs 3 units to the right.

Front

What is the slope of the line represented by the equation y = -6?

Back

0

Front

How can you find the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points.

Front

What is the slope of the line that passes through the points (2, 3) and (5, 11)?

Back

Slope = (11 - 3) / (5 - 2) = 8/3.
