Slope Basics Review

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12)

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (1, 2) and (4, 8)

Back

The slope is 2.

Front

What is the slope intercept form of the equation 4x - 8y = 72?

Back

The slope intercept form is y = 1/2x - 9.

Front

Slope is best described as_________________

Back

the steepness of a line.

Front

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

Back

The formula is m = (y2 - y1) / (x2 - x1).

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.

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.
