Y-Intercept: equations, graphs, tables

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It is the value of y when x is 0.

Front

How can 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, which represents the y-intercept.

How do you determine the y-intercept from a table of values?

Back

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

Front

What is the y-intercept of the graph represented by the point (0, 1)?

Back

(0, 1) indicates that the y-intercept is 1.

Front

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

Back

It means the line passes through the origin (0,0) on the graph.
