What does the y-intercept represent in a linear function?

Back

The y-intercept represents the initial value of the function when x = 0.

Front

What is the general form of a linear function?

Back

A linear function can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and has a constant rate of change.

Front

If w(x) = 3x - 7, what is w(7)?

Back

w(7) = 3(7) - 7 = 21 - 7 = 14.

Front

Solve for x: -19 - x = -6(3x + 6)

Back

x = -1.

Front

Identify the y-intercept of the equation y = -3x - 7.

Back

The y-intercept is -7.

Front

What type of function adds the same number each time?

Back

Linear function.

Front

What is the slope of the function f(x) = -0.75x + 12?

Back

The slope is -0.75.

Front

If a function has a positive slope, what does that indicate about the graph?

Back

It indicates that the graph rises as it moves from left to right.
