What does it mean if a line is below another line on a graph?

Back

If a line is below another line on a graph, it indicates that the value represented by that line is less than the value represented by the other line at corresponding points.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.
