Compare y-intercepts

How can you tell the y-intercept when you have a table instead of a graph?

• Count rise-over run.

• See where the y-value is zero.

• See where the x-value is zero.

• Impossible to tell.

Which has a greater y-intercept?

• A

• B

• neither

Compare the initial values of each function.

• The initial value of item I is greater than the initial value of item II.

• The initial value of item I is equal to the initial value of item II.

• The initial value of item II is greater than the initial value of item I.

Compare the initial values and rate of change of both functions.

• Both functions have the same initial value and rate of change.

• The functions have different initial values and different rates of change.

• The rates of change are the same, but the initial values differ.

• The initial values are the same, but the rates of change differ.
