Compare Slope from Two Functions

What has the GREATER rate of change. y = 5x +15 OR the graph

• y = 5x + 15

• 

Who is losing weight faster?

• Valerie

• Oscar

• Mrs. Conte

• They are losing the same amount of weight

Constant rate of change is the same thing as...

• slope

• y-intercept

Which of the key words mean constant rate of change? Select all that apply.

• begin

• each

• start

Connor and Pilar are in a rock-climbing club. They are climbing down a canyon wall. Connor starts from a cliff that is 200 feet above the canyon floor and climbs down at an average speed of 10 feet per minute. Pilar climbs down the canyon wall as shown in the table. Who climbs at a faster rate?

• Connor

• Pilar

What is the rate of change?

• y

• m

• x

• b

Find the rate of change

• 1

• 2

• 11

• Not a constant slope/Non-Linear

Compare the 4

functions shown in the box.

Which has a positive slope?

• Only Function 1

• Only Function 3

• Both functions 1 & 3

• Both functions 2 & 3

Which statement is true about the rate of change of the two functions?

• Both functions have negative rates of change.

• Both functions have positive rates of change.

• Function 1 has a negative rate of change, while that of Function 2 is positive.

• Function 1 has a positive rate of change, while that of Function 2 is negative.

Compare the two linear functions listed below and determine which has a greater slope.

• Function 1 because the slope is 3/2

• Function 2 because the slope is 1

• Function 1 because the slope is 2/3

• They are equal
