y=mx+b

Front

What does the equation y=mx+b represent?

Back

It represents the slope-intercept form of a linear equation, 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. A positive slope rises from left to right, while a negative slope falls.

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 (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What type of slope does a line with a slope of 0 have?

Back

A line with a slope of 0 is horizontal.

Front

What type of slope does a line with an undefined slope have?

Back

A line with an undefined slope is vertical.

Front

If a line has a slope of -5/4, what does this indicate about its direction?

Back

It indicates that the line falls as it moves from left to right.

Front

If a line has a slope of 4/5, what does this indicate about its direction?

Back

It indicates that the line rises as it moves from left to right.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope of a perfectly horizontal line is 0.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope of a perfectly vertical line is undefined.
