Unit 5 (TOPIC 3)

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the rise (vertical change) to the run (horizontal change).

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 negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line descends from left to right.

Front

What is the constant of proportionality (k)?

Back

The constant of proportionality (k) is the constant factor that relates two proportional quantities, expressed as y = kx.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

True or False: The unit rate and slope are the same in proportional relationships.

Back

True.

Front

What is the formula for finding the slope of a line in a graph?

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

If a line crosses the y-axis at (0, 3), what is the y-intercept?

Back

The y-intercept is 3.
