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

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, indicating the value of y when x = 0.

Front

How do you identify a positive slope on 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 on a graph?

Back

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

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where x remains constant and y can take any value.

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line, where y remains constant and x can take any value.

Front

In the equation y = 3x + 5, what is the slope?

Back

The slope is 3.

Front

In the equation y = -2x + 4, what is the y-intercept?

Back

The y-intercept is 4.

How can you determine if a graph is linear?

Back

A graph is linear if it forms a straight line.
