Intercepts of Linear Graphs

Front

What is the y-intercept of a linear graph?

Back

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

Front

How do you find the y-intercept from a linear equation?

Back

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

Front

What is the x-intercept of a linear graph?

Back

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

Front

How do you find the x-intercept from a linear equation?

Back

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

Front

What does the point (0, 3) represent on a graph?

Back

It represents the y-intercept of the line, where the line crosses the y-axis at y = 3.

Front

What does the point (2, 0) represent on a graph?

Back

It represents the x-intercept of the line, where the line crosses the x-axis at x = 2.

Front

If a line has no x-intercept, what does that mean?

Back

It means the line is parallel to the x-axis and does not cross it.

Front

If a line has no y-intercept, what does that mean?

Back

It means the line is vertical and does not cross the y-axis.

Front

What is the significance of intercepts in graphing linear equations?

Back

Intercepts help to quickly identify key points on the graph and understand the line's behavior.

Front

How can you determine if a point is an intercept?

Back

A point is an intercept if either its x-coordinate or y-coordinate is zero.
