Slope

Front

What is slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

Front

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

Back

The formula to calculate the slope (m) of a line is: m = (y2 - y1) / (x2 - x1).

Front

What type of slope is represented when a line rises from left to right?

Back

Positive slope.

Front

What type of slope is represented when a line falls from left to right?

Back

Negative slope.

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 2, what does this mean?

Back

For every 2 units the line rises vertically, it moves 1 unit horizontally.

Front

Calculate the slope of the line that passes through the points (1, 2) and (3, 6).

Back

The slope is 2.

If the slope of a line is 3, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it is -1/3.
