Linear Functions Flashcardizz

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 function?

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 function?

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 a linear function be represented?

Back

A linear function can be represented in four ways: as an equation, a graph, a table, and using words.

Front

What is the opposite operation of addition?

Back

The opposite operation of addition is subtraction.

Front

If y = 2x + 4, what is y when x = 2?

Back

y = 2(2) + 4 = 8.

Front

If y = 3x - 1, what is y when x = 0?

Back

y = 3(0) - 1 = -1.

Front

What is the value of y when x = -1 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? A) Using words B) As a coefficient C) As an equation D) Using a graph E) As a table

Back

B) As a coefficient.

What is the value of y when x = 2 in the equation y = -3x + 6?

Back

y = -3(2) + 6 = 0.
