8th grade module 5

Front

What formula do we use when finding slope on a graph?

Back

Rise/Run

Front

How can you determine if a graph is proportional or non-proportional?

Back

A graph is proportional if it passes through the origin and has a constant slope; otherwise, it is non-proportional.

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

What does the slope of a line represent?

Back

The slope of a line represents the rate of change between the two variables on the graph.

Front

How do you calculate the slope of a line given two points?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the significance of a slope of 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in the y-value as the x-value changes.

Front

What does a positive slope indicate about a line?

Back

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

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.

Front

What is the relationship between slope and steepness of a line?

Back

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

Front

How can you identify the unit rate from a proportional relationship?

Back

The unit rate can be identified by dividing the total quantity by the number of units, giving the amount per one unit.
