Slope Review

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) where b is the value of the y-coordinate.

Front

Which ordered pair represents a y-intercept?

Back

(0, 4)

Front

How do you calculate the slope of a line?

Back

Slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

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 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 a line has a slope of 4/5, what does this mean?

Back

For every 5 units moved horizontally to the right, the line moves up 4 units.
