Warm Up 12/11/2024 X intercept and Y intercept

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.

Front

What is the y-intercept?

Back

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

Front

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.

Front

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

Back

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

Front

What are the x- and y-intercepts of the equation y = 2x - 6?

Back

The x-intercept is (3, 0) and the y-intercept is (0, -6).

Front

What does the point (5, 0) represent on a graph?

Back

The point (5, 0) represents the x-intercept, where the graph crosses the x-axis.

Front

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

Back

The point (0, 3) represents the y-intercept, where the graph crosses the y-axis.

Front

If a graph has an x-intercept of 4, what does this mean?

Back

It means that the graph crosses the x-axis at the point (4, 0).

Front

If a graph has a y-intercept of -2, what does this mean?

Back

It means that the graph crosses the y-axis at the point (0, -2).

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 linear function.
