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 + 2?

Back

The slope (m) is 3.

Front

What is the y-intercept in the equation y = -2x + 5?

Back

The y-intercept (b) is 5.

Front

How do you identify a positive slope in a linear equation?

Back

A positive slope means that as x increases, y also increases. This is indicated by a positive value of m.

Front

How do you identify a negative slope in a linear equation?

Back

A negative slope means that as x increases, y decreases. This is indicated by a negative value of m.

Front

What is the slope of the line represented by the equation y = 0.5x - 1?

Back

The slope (m) is 0.5.

Front

If the equation of a line is y = 4x + 1, what is the slope?

Back

The slope (m) is 4.

Front

What does the term 'slope' refer to in a linear equation?

Back

The slope refers to the steepness of the line, calculated as the rise over run (change in y over change in x).

Front

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

Back

The slope (m) is -1.

Front

In the equation y = mx + b, what does 'b' represent?

Back

The y-intercept, which is the point where the line crosses the y-axis.
