Slope-Intercept Form

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

Identify the slope in the equation y = 3/2x + 3.

Back

The slope is 3/2.

Front

Identify the y-intercept in the equation y = 3/2x + 3.

Back

The y-intercept is (0, 3).

Front

What does the letter 'b' represent in the slope-intercept form?

Back

The letter 'b' represents the y-intercept of 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 does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 7/5x + 2?

Back

The slope is 7/5.
