FLASHCARD QUESTION

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.

2.

FLASHCARD QUESTION

Front

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

Back

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

FLASHCARD QUESTION

Front

What is the y-intercept in the equation of a linear function?

Back

The y-intercept is the value of y when x is 0. It is represented by the term 'b' in the equation y = mx + b.

4.

FLASHCARD QUESTION

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

FLASHCARD QUESTION

Front

What is the equation of a line with a slope of 4 and a y-intercept of 16?

Back

The equation is y = 4x + 16.

6.

FLASHCARD QUESTION

Front

If a linear function has a slope of -2, what does this indicate about the line?

Back

A slope of -2 indicates that the line is decreasing; for every 1 unit increase in x, y decreases by 2 units.

FLASHCARD QUESTION

Front

What is the standard form of a linear equation?

Back

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