Finding X and Y Intercepts from a Graph

Front

What is the y-intercept of a graph?

Back

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

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the graph intersects the y-axis.

Front

What is the x-intercept of a graph?

Back

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

Front

How do you find the x-intercept from a graph?

Back

To find the x-intercept, look for the point where the graph intersects the x-axis.

Front

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

Back

It represents the y-intercept, indicating that the graph crosses the y-axis at -2.

Front

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

Back

It represents the x-intercept, indicating that the graph crosses the x-axis at -2.

Front

What are the roots of a graph?

Back

The roots are the x-intercepts of the graph, where the graph touches or crosses the x-axis.

Front

What is the significance of the x-intercept in a real-world context?

Back

The x-intercept can represent a point where a quantity reaches zero, such as profit or population.

Front

What is the significance of the y-intercept in a real-world context?

Back

The y-intercept can represent the starting value of a quantity when the independent variable is zero.

Front

If a graph has a y-intercept of 7, what does this mean?

Back

It means that when x = 0, the value of y is 7.
