• y

Q 12 & 32: Describe the relationship between two variables

• y is a constant

• x is dependent on on y

• y is the independent variable

• y is dependent on x

Q5: What does rate of change mean?

Q2: What type of graph is shown and what is the equation?

• linear decay

  y=mx+b

• exponential decay

  y=a(b)^x

• exponential growth

  y=mx+b

• exponential decay

  y=-a(b)^x

Q24: If you chose A. as your answer, what did you forget to do?

• read the question - it was asking you for the TRANSLATION of the graph!

• A. is the correct answer

• the slope should have been negative

• the y-intercept should have been positive

Q16: What was step 1?

• move a to the other side

• cancel the constant

• distribute

  shade above

• dotted

  shade above

  shade below

Q1: What does RANGE mean and how do we read it on a graph?

• y-values

  top to bottom

• x-values

  left to right

• y-values

  bottom to top

• x-values

  bottom to top

Q52: What does a negative sign in front of 'm' do to transform a graph?

• makes the graph more steep

• makes the graph less steep

• shifts the graph down

• reflects the graph
