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 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 function.

Front

What is the opposite operation of addition?

Back

The opposite operation of addition is subtraction.

Front

What is the opposite operation of multiplication?

Back

The opposite operation of multiplication is division.

Front

If y = 2x + 4, what is y when x = -1?

Back

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

Front

If y = 3x - 5, what is y when x = 2?

Back

y = 3(2) - 5 = 1.

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 = 0 in the equation y = -2x - 6?

Back

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