What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It is represented as (0, b), where b is the value of the y-coordinate.

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

Back

To find the y-intercept from a linear equation in the form y = mx + b, the y-intercept is the value of b.

Front

What does the y-intercept represent in a real-world context?

Back

The y-intercept can represent the starting value of a situation in real-world problems, such as the initial amount of money in a bank account.

Front

If a line has a y-intercept of (0, 3), what does this mean?

Back

It means that when x = 0, the value of y is 3. The line crosses the y-axis at the point (0, 3).

Front

What is the y-intercept of the equation y = 2x + 5?

Back

The y-intercept is (0, 5). This is found by setting x = 0 in the equation.

Front

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

Back

You can determine the y-intercept by locating the point where the line intersects the y-axis.

Front

What is the y-intercept of the equation y = -3x + 1?

Back

The y-intercept is (0, 1). This is found by setting x = 0 in the equation.

Front

If a graph shows a y-intercept at (0, -2), what does this indicate?

Back

It indicates that when x = 0, the value of y is -2, meaning the line crosses the y-axis at that point.

Front

What is the significance of a positive y-intercept?

Back

A positive y-intercept indicates that the line starts above the origin on the y-axis.

Front

What is the significance of a negative y-intercept?

Back

A negative y-intercept indicates that the line starts below the origin on the y-axis.
