If a babysitter charges a flat fee plus an hourly rate, how would you represent this with an equation?

Back

You would represent it as C = mh + b, where m is the hourly rate, h is the number of hours, and b is the flat fee.

Front

What is the significance of the slope in a real-world context?

Back

The slope represents the rate of change, indicating how much y changes for a unit change in x.

Front

How do you convert a word problem into a linear equation?

Back

Identify the variables, determine the fixed and variable costs, and express the relationship in the form y = mx + b.
