Finding x and y-intercepts

Front

What is the y-intercept of a function?

Back

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

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.

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

Back

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

What is the x-intercept of the equation 2x + 4y = 8?

Back

(4, 0) - Set y = 0, then x = 4.

Front

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

Back

It represents the y-intercept of the function.

Front

What does the point (-1, 0) represent in a graph?

Back

It represents the x-intercept of the function.
