What is the slope of the line that passes through the points (0, -2) and (3, -4)?

Back

-2/3

Front

What is the definition of slope?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If f(x) = 3x + 1 and g(x) = (3x + 1) + 4, what transformation occurred?

Back

Shifted (translated) up 4 units.

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.
