What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together. It expresses how much of one quantity corresponds to one unit of another quantity.

Front

How do you calculate the unit rate from a given price and quantity?

Back

To calculate the unit rate, divide the total price by the number of items. For example, if 10 tickets cost $15, the unit rate is $15 ÷ 10 = $1.50 per ticket.

What does the slope of a line represent in a graph?

Back

The slope of a line represents the rate of change between the two variables plotted on the graph. It indicates how much one variable changes for a unit change in another variable.

Front

How do you find the slope using two points on a line?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What is a slope triangle?

Back

A slope triangle is a right triangle formed by the rise and run of a line on a graph, used to visually represent the slope.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

How do you interpret the equation y = 20x in the context of Susan's elevator travel?

Back

In this equation, y represents the number of floors traveled, and x represents the time in minutes. The unit rate is 20 floors per minute.

Front

What is the rate of change in a linear relationship?

Back

The rate of change is the ratio of the change in the dependent variable to the change in the independent variable, often represented by the slope.

Front

How do you write an equation from a given rate?

Back

To write an equation from a given rate, identify the relationship between the variables and express it in the form y = mx, where m is the rate.
