Identifying Y-intercept(Graphs)

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph.

Front

How can 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 mean?

Back

A y-intercept of 0 means that the line crosses the origin (0,0) on the graph.

Front

If a line has a y-intercept of 6, what does this indicate?

Back

It indicates that the line crosses the y-axis at the point (0, 6).

Front

What is the significance of the y-intercept in real-world applications?

Back

The y-intercept can represent the starting value of a situation in real-world contexts, such as initial costs or starting populations.

Front

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

Back

To determine the y-intercept from a graph, locate the point where the line intersects the y-axis.

Front

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

Back

The y-intercept is 4, which is the value of b in the equation.

Front

Can a line have more than one y-intercept?

Back

No, a line can only have one y-intercept.

Front

What does a negative y-intercept indicate?

Back

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

Front

If a line has a y-intercept of -5, what does this indicate?

Back

It indicates that the line crosses the y-axis at the point (0, -5).
