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 = 3x + 6?

Back

3

Front

What does the slope (m) indicate in a linear equation?

Back

The slope indicates the steepness and direction of the line; a positive slope means the line rises, while a negative slope means it falls.

Front

What is the y-intercept in the equation y = 2x - 4?

Back

-4

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = -2x - 6?

Back

-2

Front

If a line has a slope of 0, what does that indicate about the line?

Back

It indicates that the line is horizontal.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

Which equation represents a line with a positive slope?

Back

y = 2x + 1.

Front

What is the slope of the line represented by the equation y = 1/2x + 3?

Back

1/2.
