Front

What does the equation x = -9 represent?

Back

A vertical line.

Front

What is the domain of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

D: {-4, 0, 1, 2}

Front

What does 'm' represent in the equation y = mx + b?

Back

The slope of the line.

Front

What is the range of the graph with the set {1,3,4,5,6}?

Back

Range: {3, 4, 5, 6}

Front

What is the x-intercept of the line?

Back

(-1, 0)

Front

What is the definition of a horizontal line?

Back

A line that runs left to right and has a slope of 0.

Front

What is the definition of a vertical line?

Back

A line that runs up and down and has an undefined slope.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept in the equation y = mx + b?

Back

The value of y when x = 0.

Front

What is the formula for finding the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.
