Unit Rate as SLOPE- Review Game

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something, such as miles per hour or dollars per item.

Front

How do you find the slope of a line?

Back

The slope of a line is found by taking the difference in the y-coordinates (rise) and dividing it by the difference in the x-coordinates (run) between two points on the line.

Front

What does a slope of 0 indicate about a line?

Back

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

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value of the ratio of two proportional quantities, often represented as 'k' in the equation y = kx.

Front

If a line has a slope of 2, what does this mean in terms of rise over run?

Back

A slope of 2 means that for every 1 unit you move to the right (run), the line rises 2 units (rise).

Front

Calculate the unit rate: You spend $40 on 5 pounds of concrete. What is the unit rate in dollars per pound?

Back

$8 per pound.

Front

Which of the following is a unit rate: 10 miles / 2 hours, $6 for each hour, 1 box / $3, 15 pounds every 5 servings?

Back

$6 for each hour.

Front

What is the slope of a line that passes through the points (1, 3) and (4, 9)?

Back

The slope is 2.

Front

How can you express a unit rate as a fraction?

Back

A unit rate can be expressed as a fraction by placing the quantity in the numerator and the unit in the denominator, such as 8 dollars/1 pound.

Front

What is the relationship between slope and unit rate?

Back

The slope of a line in a graph represents the unit rate of change between the two variables represented on the axes.
