Front

What is the y-intercept of a line?

Back

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

Front

How do you find the y-intercept from a graph?

Back

Look for the point where the line intersects the y-axis.

Front

What is the value of the y-intercept in the equation y = mx + b?

Back

The value of the y-intercept is represented by 'b'.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How is slope calculated between two points (x1, y1) and (x2, y2)?

Back

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

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

What is the formula for the slope-intercept form of a line?

Back

The formula is y = mx + b, where m is the slope and b is the y-intercept.
