What's the Y-Intercept?
In a linear equation, the y-intercept is really just the point where the graph of the line crosses the y-axis.

What's the X-Intercept?
In a linear equation, the x-intercept is really just the point where the graph of the line crosses the x-axis.

How Do You Check if a Point is on a Line If You Have a Graph?
The instructor demonstrates how to verify that a given point does or does not lie on the line of a given equation. She draws a graph (the axis lines need arrow ends) and plots the given linear equation. She then plots the coordinate...

How Do You Find the X- and Y-Intercepts of a Line in Slope-Intercept From?
Find the x and y intercepts in a given linear equation written in slope intercept form. Piece of cake! There are just two things to do. First, substitute 0 for x and solve to find the y-value. Then substitute 0 for y to find the value of...

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 Write an Equation of the Line in Slope-Intercept Form If You Have a Graph?
An equation can be gotten from the graph of a line. Yes, it can. Watch this video and follow the instructor as she goes step-by-step explaining and illustrating how to get an equation from information from the graph of a line.

How Do You Write an Equation of a Line in Slope-Intercept Form If You Have Two Points?
Given two points on a line, write an equation in slope-intercept form. But what's the slope? Oh, you have to figure out the slope first. That can be done given the two points. Just use the rise over run slope formula. This isn't so hard...
