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 cost per item.

How do you find the unit rate from a graph?

Back

To find the unit rate from a graph, identify the change in the y-value (output) and the change in the x-value (input) between two points, then divide the change in y by the change in x.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept represents the value of y when x is zero, indicating the starting point of the line on the y-axis.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio between variables and pass through the origin (0,0), while non-proportional relationships do not.

Front

How can you identify the y-intercept from a table of values?

Back

The y-intercept can be identified as the value of y when x is equal to zero.

Front

What does the slope (m) in the equation y = mx + b represent?

Back

The slope (m) represents the rate of change of y with respect to x, indicating how much y increases or decreases for each unit increase in x.

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant of the line.

How do you determine if a relationship is linear?

Back

A relationship is linear if it can be represented by a straight line on a graph, meaning it has a constant rate of change.
