FLASHCARD QUESTION

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

FLASHCARD QUESTION

Front

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

Back

The y-intercept can be found by setting x = 0 in the equation of the line and solving for y.

FLASHCARD QUESTION

Front

What is the domain of a linear function?

Back

The domain of a linear function is all real numbers, as there are no restrictions on the values that x can take.

5.

FLASHCARD QUESTION

Front

What is the range of a linear function?

Back

The range of a linear function is also all real numbers, as the output (y) can take any value depending on the input (x).

FLASHCARD QUESTION

Front

How do you write the equation of a line given a slope and a point?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

FLASHCARD QUESTION

Front

What is the point-slope form of a linear equation?

Back

The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
