Favela's rise over run

Front

What is the y-axis on the coordinate plane?

Back

The y-axis is a vertical line (up and down) on the coordinate plane.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise (change in y) over the run (change in x).

Front

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

Back

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

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What is the x-axis on the coordinate plane?

Back

The x-axis is a horizontal line (side to side) on the coordinate plane.

Front

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

Back

The slope is 2.

Front

What is the slope of the line represented by the equation y = -4/3x + 1?

Back

The slope is -4/3.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal.

Front

If a line has an undefined slope, what does that mean?

Back

An undefined slope means the line is vertical.
