How Do You Find the X- and Y-Intercepts of a Line If You Have a Graph?

6th - 12th
The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.

How Do You Use a Graph to Reflect a Figure Over the Y-Axis?

6th - 10th
A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the y-axis) and make the calculations to flip the figure.
