Slope Review

Front

What is the definition of slope?

Back

Slope is defined as the ratio of the rise (vertical change) to the run (horizontal change) between two points on a line.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

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

Back

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

Front

What is the slope of a line that passes through the points (2, 3) and (5, 3)?

Back

The slope is 0.

Front

What is the slope of a line that passes through the points (1, 2) and (1, 5)?

Back

The slope is undefined.

Front

If a line has a slope of -2, what does this indicate about its direction?

Back

A slope of -2 indicates that the line descends from left to right.

Front

What is the y-intercept of a line?

Back

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

Front

If a line has a y-intercept of -3, what does this mean?

Back

It means that the line crosses the y-axis at the point (0, -3).

Front

What is the slope of the line represented by the equation y = 4x + 1?

Back

The slope is 4.
