Slope Intercept Form (Final Practice)

Front

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

Back

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

Front

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

Back

The slope (m) represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What does the y-intercept (b) represent in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

How do you identify a positive slope from a graph?

Back

A positive slope rises from left to right, indicating that as x increases, y also increases.

Front

How do you identify a negative slope from a graph?

Back

A negative slope falls from left to right, indicating that as x increases, y decreases.

Front

What is the equation of a horizontal line in slope-intercept form?

Back

The equation of a horizontal line is y = b, where b is the constant value of y.

Front

What is the equation of a vertical line in slope-intercept form?

Back

Vertical lines cannot be expressed in slope-intercept form; they are represented as x = a, where a is the constant value of x.

Front

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

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

If a line has an undefined slope, what does that indicate?

Back

An undefined slope indicates a vertical line, meaning x remains constant while y changes.

Front

How do you convert the equation y = 3x + 2 to slope-intercept form?

Back

The equation is already in slope-intercept form: y = mx + b, where m = 3 and b = 2.
