X and Y intercepts

Front

What is the x-intercept?

Back

The x-intercept is the point where a graph crosses the x-axis. At this point, the value of y is 0.

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

Back

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

What is the x-intercept of the equation 3x + 8y = 24?

Back

(8, 0) - Set y = 0, then solve for x.

What is the y-intercept of the equation 3x + y = 5?

Back

(0, 5) - Set x = 0, then solve for y.

What does the point (4, 0) represent on a graph?

Back

It represents the x-intercept, where the graph crosses the x-axis.

Front

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

Back

It represents the y-intercept, where the graph crosses the y-axis.

Front

If a line has an x-intercept of 12, what does this mean?

Back

It means the line crosses the x-axis at the point (12, 0).

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 behavior of the line.
