What is the essential question for this lesson?

• How do I solve equations?

• What is the rate of change?

• How do I compare functions?

• How do I find the slope?

Which formula is used to find the slope?

• y2 - y1 / x2 - x1

• x2 - x1 / y2 - y1

• rise + run

• y = mx + b

What is the Larkin L method used for?

• Finding the y-intercept

• Calculating the slope

• Graphing functions

• Solving quadratic equations

In the equation y = mx + b, what does 'm' represent?

• The slope

• The constant term

• The y-intercept

• The x-intercept

If you have two points (5, 7.5) and (6, 9), what is the slope?

• 0.5

• 2

• 1.5

• 1

How do you determine the rate of change from a table?

• By adding the x-values

• By subtracting the y-values

• By calculating the change in y over the change in x

• By finding the y-intercept

What is the rate of change for Ty if he makes 7 signs every 2 hours?

• 7 signs per hour

• 3 signs per hour

• 2 signs per hour

• 3.5 signs per hour

Who makes signs faster, Ty or Harrison, if Harrison's rate is 3.75 signs per hour?

• Ty

• Harrison

• Both make signs at the same rate

• Cannot be determined

What is the slope of the equation y = 3x + 9?

• 9

• 3

• 1/3

• 6

What should you do if you are not sure how to compare two rates of change?

• Use the Larkin L method

• Add the rates together

• Convert them to decimal form

• Ignore the rates
