Slope-Intercept Form

Front

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

Back

The slope (m) represents the rate of change of y with respect to x in the equation of the form y = mx + b.

Front

What does the y-intercept represent in the slope-intercept form?

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

Back

The slope is 2.

The slope is -3.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of 1/2, what does this indicate about the relationship between x and y?

Back

For every 2 units increase in x, y increases by 1 unit.
