Finding the y intercept on a graph

Front

What is the y-intercept of a line?

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

Back

The y-intercept can represent the starting value of a situation when the independent variable is zero.

Front

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

Back

It means that when x = 0, the value of y is 4.

Front

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

Back

Locate the point where the line intersects the y-axis; this point's y-coordinate is the y-intercept.

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

What is the y-intercept of the line represented by the equation y = -x + 5?

Back

The y-intercept is 5.

Front

If a line crosses the y-axis at -2, what is the y-intercept?

Back

The y-intercept is -2.

Front

What is the significance of a y-intercept of 0?

Back

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

Front

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

Back

Look for the row where x = 0; the corresponding y value is the y-intercept.
