Graphing using Intercepts

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis, represented as (x, 0).

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What does the equation of a line in slope-intercept form look like?

Back

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

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of the line, calculated as the rise over run (change in y over change in x).

How can you graph a line using intercepts?

Back

To graph a line using intercepts, plot the x-intercept and y-intercept on the graph and draw a line through these points.

What is the significance of the point (0, 0) in graphing?

Back

The point (0, 0) is the origin, where the x-axis and y-axis intersect.

Front

What does it mean if a line has a positive slope?

Back

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

Front

What does it mean if a line has a negative slope?

Back

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