Graph y=mx+b

Front

What does the equation y = mx + b represent?

Back

It represents the equation of a straight line, where m is the slope and b is the y-intercept.

Front

What is the slope in the equation y = mx + b?

Back

The slope (m) indicates the steepness and direction of the line.

Front

What does a positive slope indicate about a line?

Back

A positive slope means that as x increases, y also increases, resulting in an upward slant.

Front

What does a negative slope indicate about a line?

Back

A negative slope means that as x increases, y decreases, resulting in a downward slant.

Front

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

Back

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

Front

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

Back

The slope is calculated as (y2 - y1) / (x2 - x1).

Front

What type of slope does the equation y = 3x + 2 have?

Back

It has a positive slope.

Front

What type of slope does the equation y = -2x + 3 have?

Back

It has a negative slope.

Front

What does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line.
