Front

What does a rate of change represent in a linear equation?

Back

It represents how much the dependent variable changes for a unit change in the independent variable.

Front

If a table shows a constant rate of change of 5, what does that imply about the relationship between the variables?

Back

It implies that for every 1 unit increase in the independent variable, the dependent variable increases by 5.

Front

What is the formula to find the unit rate?

Back

Unit Rate = Total Quantity / Total Time or Total Cost.

Front

If y = mx + b, what do m and b represent?

Back

m is the slope (rate of change), and b is the y-intercept (value of y when x=0).

Front

How do you determine the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points.

Front

What is the significance of the y-intercept in a linear equation?

Back

It indicates the starting value of y when x is zero.
