What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is and the direction it goes.

Front

What are the types of slopes?

Back

1. Positive slope: line rises from left to right. 2. Negative slope: line falls from left to right. 3. Zero slope: horizontal line. 4. Undefined slope: vertical line.

What is the equation of a line with a slope of 2 and a y-intercept of 3?

Front

What does it mean if two lines have the same slope?

Back

If two lines have the same slope, they are parallel and will never intersect.

Front

How do you determine if a slope is positive or negative from a graph?

Back

If the line rises as it moves from left to right, the slope is positive. If it falls, the slope is negative.
