Find the Y-Intercept

Front

What is the y-intercept?

Back

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

Front

How do you find the y-intercept from a table of values?

Back

Look for the value of y when x is 0. This point is the y-intercept.

Front

What is the y-intercept of the function f(x) = 2x + 3?

Back

(0, 3) because when x = 0, f(0) = 3.

Front

What is the y-intercept of the function f(x) = -x + 5?

Back

(0, 5) because when x = 0, f(0) = 5.

Front

If a function has no y-intercept, what does that mean?

Back

It means the line is vertical and does not cross the y-axis.

Front

What is the y-intercept of the function f(x) = 4?

Back

(0, 4) because it is a horizontal line at y = 4.

Front

How can you determine the y-intercept from a graph?

Back

Find the point where the line intersects the y-axis.

Front

What does a negative y-intercept indicate about a function?

Back

It indicates that the line crosses the y-axis below the origin.

Front

What is the y-intercept of the function f(x) = 3x - 2?

Back

(0, -2) because when x = 0, f(0) = -2.

Front

How do you express the y-intercept in coordinate form?

Back

As (0, y) where y is the value of the function when x = 0.
