Slope Between Two Points and Tables

Front

What is the formula to calculate the slope (m) between two points (x1, y1) and (x2, y2)?

Back

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

Front

Given the points (2, -4) and (3, 1), what is the slope?

Back

Front

What does a positive slope indicate about a line on a graph?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that as x increases, y decreases.

Front

If the slope of a line is zero, what does this mean about the line?

Back

The line is horizontal.

Front

If the slope of a line is undefined, what does this mean about the line?

Back

The line is vertical.

Front

Determine the slope of the line that passes through the points (1, 2) and (5, 6).

Back

1

Front

What is the slope of a line that goes down from left to right?

Back

Negative slope.

Front

Given the points A(-12, 16) and B(-31, 17), what is the x-coordinate of point B?

Back

-31

Front

How do you interpret a slope of 4?

Back

For every 1 unit increase in x, y increases by 4 units.
