Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope (m) represent in a linear equation?

Back

The slope (m) represents the rate of change of the function. It indicates how much y changes for a unit change in x.

Front

What is the y-intercept (b) in a linear equation?

Back

The y-intercept (b) is the value of y when x = 0. It is the point where the line crosses the y-axis.

Front

How can you represent a linear function using a table?

Back

A linear function can be represented in a table by listing pairs of x and y values that satisfy the linear equation.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C, where A, B, and C are constants.

Front

If x = 1, what is y in the equation y = 2x - 4?

Back

y = 2(1) - 4 = -2.

Front

If x = -1, what is y in the equation y = 2x + 4?

Back

y = 2(-1) + 4 = 2.

Front

Which of the following is NOT a way to represent a function?

Back

As a coefficient.

Front

What is a characteristic of a linear equation?

Back

Graphs as a straight line.

Front

How do you find the value of y for a given x in a linear equation?

Back

Substitute the value of x into the equation and solve for y.
