Slope and Y-intercept from the GRAPH only

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) in the coordinate plane.

Front

How do you identify the slope from a graph?

Back

The slope is determined by the rise over run, which is the change in y divided by the change in x between two points on the line.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no change in y as x changes.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the change in x is 0, leading to division by zero.

Front

How do you write the slope-intercept form of a line?

Back

Front

What does the term 'proportional' mean in relation to a graph?

Back

A proportional relationship means that the line passes through the origin (0,0) and has a constant slope.

Front

What does the term 'non-proportional' mean in relation to a graph?

Back

A non-proportional relationship means that the line does not pass through the origin and has a y-intercept other than 0.

Front

How can you determine if a graph is proportional or non-proportional?

Back

Check if the line passes through the origin. If it does, it is proportional; if it does not, it is non-proportional.
