Slope: Rise over Run

Front

What is the formula for calculating slope?

Back

Slope = Rise over Run

Front

What does 'rise' refer to in the context of slope?

Back

Rise refers to the vertical change between two points on a line.

Front

What does 'run' refer to in the context of slope?

Back

Run refers to the horizontal change between two points on a line.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the slope of a line that rises 4 units and runs 1 unit?

Back

The slope is 4/1.

Front

What is the slope of a line that rises 4 units and runs 5 units?

Back

The slope is 4/5.

Front

What does it mean if a slope is undefined?

Back

An undefined slope occurs when a line is vertical, meaning there is no horizontal change (run = 0).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If a line has a slope of -3, what does this indicate about its direction?

Back

A slope of -3 indicates that the line descends from left to right.

Front

What is the relationship between slope and steepness?

Back

The greater the absolute value of the slope, the steeper the line.
