Slope flashcard P458

Front

What is the point where the x- and y-axis intersect?

Back

The origin.

Front

Which axis is horizontal?

Back

The x-axis.

Front

What is the y-intercept of the line represented by the point (0,-3)?

Back

(0,-3) is the y-intercept.

Front

What type of slope does a vertical line have?

Back

Undefined slope.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

3/2.

Front

What is the definition of slope?

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the x-intercept of a line?

Back

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