Finding the y intercept on a graph

Front

What is the y-intercept of a line?

Back

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

Front

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 a y-intercept of 0 indicate?

Back

A y-intercept of 0 indicates that the line passes through the origin (0,0).

Front

If a line has a y-intercept of -4, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -4).

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 = 0.

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 = -x - 2?

Back

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

Front

If a graph shows a y-intercept at (0, 5), what is the y-intercept value?

Back

The y-intercept value is 5.

Front

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

Back

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