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

Take graphing outside and make a giant coordinate plane to plot your human points. Young graphers are each given a coordinate for a particular shape and asked to make the geometrical shapes one by one. Those not plotted are to write down...

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

Given a linear equation in standard form, find the x-intercept and y-intercept. In this video, Sal shows how to set x = 0 and solve the y-intercept and how to set y = 0 and find the x-intercepts.

Here is a fairly basic video that uses three equations, each written in slope-intercept form, to determine whether the lines are parallel. Sal graphs each equation on the same coordinate plane to show how their slopes compare. The video...

There are many pieces and many parts to this problem. It seems simple enough to write an equation in slope-intercept form. In this problem, there is a given table of values and information from this table is used to get an equation...

To find the equation of a vertical line you need to use x=b to determine the equation. This tutorial explains the use of formula x=b to find a value for an unknown y. The explanation of this concept is rushed making this tutorial only...

Given a linear equation, find the x-intercept and the y-intercept to graph the line. Not sure what to do or where to start? Watch this video and see the instructor break it down and make it understandable.

When looking at the coordinate pairs for an horizontal line, all the y-values will be equal. Yes, the same, no matter what the x-value is. And the line will never cross the x-axis. Check out this tutorial video to see what that actually...

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.

Given algebraic, tabular, or graphical representations of linear functions, the student will determine the intercepts of the graphs and the zeros of the function.
