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.

Back

The y-intercept is 5.

Front

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

Back

To find the y-intercept from a table, look for the row where x = 0. The corresponding y value is the y-intercept.

Front

What does a positive y-intercept indicate on a graph?

Back

A positive y-intercept indicates that the line crosses the y-axis above the origin.

Front

What does a negative y-intercept indicate on a graph?

Back

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