What does the variable "m" represent in this equation?
"m" is the slope or rate of change
What does the variable "b" represent in this equation?
"b" is the y-intercept
What do the variables "x" and "y" represent in this equation?
"x" and "y" represent a set a coordinate pairs
Which diagram represents a function?
Mapping Diagram A
Explain why this is NOT a function.
The input of 2 is paired with more than one output.
Using the equation y = x² + 2, write the correct out values for each input.
6, 3, 2, 3, 6
What is the slope of this line?
1/2

Marshall and Claire belong to an adventure club. The following equations represent how much money they have remaining in their bank accounts after each monthly payment. Based on the equations, whose monthly payments are CHEAPER?
Claire's monthly dues are cheaper ($15 per month is cheaper than $18 per month)
Before starting the membership to his adventure club, Marshall had $550 in his bank account. How much money did Claire have to start with?
$480 (the y-intercept shows the starting amount)
Find the rate of change (slope) for the information in the table below if the time represents "x" and the account balance represents "y".
-15/1 or -15
What is the volume of this cylinder? Round your answer to the nearest tenth.
Volume = 339.1 ft³
What is the volume of this cone? Round your answer to the nearest tenth.
Volume = 134.0 in³
What is the volume of this sphere? Round your answer to the nearest tenth.
Volume = 267.9 cm³
If the two cylinders below have the same radius, would they also have the same volume? Explain.
No, because they have different heights and both the radius and the height measurements are used in the volume formula for a cylinder.
