X & Y Intercepts

Front

What are X and Y intercepts?

Back

The X intercept is the point where a graph crosses the X-axis (y=0), and the Y intercept is where it crosses the Y-axis (x=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.

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 is the X intercept of the equation y = 2x + 4?

Back

The X intercept is -2.

Front

What is the Y intercept of the equation y = 2x + 4?

Back

The Y intercept is 4.

Front

Identify the graph with a X intercept of -2 and Y intercept of 2.

Back

The graph of the equation y = -x - 2.

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 is 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

What does it mean if a graph has no X intercept?

Back

It means the graph does not cross the X-axis, indicating that the function does not have real roots.

Front

What does it mean if a graph has no Y intercept?

Back

It means the graph does not cross the Y-axis, which can occur in vertical lines.
