find y intercept

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, y) where y is the value of the function when x = 0.

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept from an equation in the form y = mx + b, identify the value of b. This value is the y-intercept.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant of the line.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant of the line.

Front

In the equation y = -2x + 5, what is the y-intercept?

Back

The y-intercept is 5, represented as the point (0, 5).

Front

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

Back

It means that the line crosses the y-axis at the point (0, -3).

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept helps to understand the starting value of a function when x is zero.

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 line represented by the equation y = 3?

Back

The y-intercept is (0, 3), meaning the line is horizontal and crosses the y-axis at 3.

Front

In the equation y = -x + 2, what is the y-intercept?

Back

The y-intercept is 2, represented as the point (0, 2).
