How Do You Find the X- and Y-Intercepts of a Line If You Have a Graph?
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 Coordinates to Reflect a Figure Over the Y-Axis?
Perform a reflection of a figure over the y-axis. This seems pretty straightforward. But also learn how to use the coordinates to reflect a figure.

What is a Line of Reflection?
Line of reflection is basically a geometry term used in the transformation of figures. It identifies the line on the graph that you reflect a figure over. The line can be vertical, horizontal, and diagonal. Actually, it can be any line...

How Do You Graph a Line If You're Given the Slope and the Intercept?
You have been given the value for the y-intercept and the slope of a line. Now you have to graph it. So draw a graph, plot your y-intercept and then count out your movement for slope. Don't forget to connect the dots and draw a line...

What are the Coordinate Axes?
The coordinate axes are the x-axis, which is the horizontal axis, and the y-axis, which is the vertical axis. Remember, these axes go on forever.
