Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It occurs when the x-coordinate is 0.

Front

Identify the y-intercept of the point (0, 5).

Back

The y-intercept is (0, 5).

Front

How do you model a savings account with a starting amount and monthly savings?

Back

The function is modeled as y = mx + b, where m is the monthly savings, x is the number of months, and b is the initial amount.

Front

If Bob saves $40 per month starting with $150, what is the function that models his savings?

Back

y = 40x + 150.

Front

What does the variable 'w' represent in the equation 7w + 30 = -3w + 5(w - 2)?

Back

The variable 'w' represents an unknown quantity that we need to solve for.

Front

Solve the equation: 7w + 30 = -3w + 5(w - 2). What is w?

Back

w = -8.

Front

Where does Santa Claus live according to popular culture?

Back

Santa Claus lives at The North Pole.

Front

What is the initial value in a function or table?

Front

If a table shows values starting at 6, what is the initial value?

Back

The initial value is 6.

Front

What is the general form of a linear function?

Back

The general form of a linear function is y = mx + b, where m is the slope and b is the y-intercept.
