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 = 2x + 3?

Back

The slope (m) is 2.

Front

What is the y-intercept in the equation y = -4x + 1?

Back

The y-intercept (b) is 1.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

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 is the y-intercept of the line represented by the equation y = 5?

Back

The y-intercept is (0, 5).

Front

If the slope of a line is 0, what does that tell you about the line?

Back

The line is horizontal.

Front

If the slope of a line is undefined, what does that tell you about the line?

Back

The line is vertical.

Front

What is the slope of the line represented by the equation y = -3x + 4?

Back

The slope (m) is -3.
