WebGraphing linear equations questions deal with linear equations and their graphs in the xy xy -plane. For example, the graph of y=2x-1 y = 2x −1 is shown below. In this lesson, we'll learn to: Identify features of linear graphs from their equations Write linear equations based on graphical features WebOne way to plot a line is to plot any two points that are on the line, and for an equation in standard from like this one, two easy points to find at the x and y intercepts--the values where x=0 and y=0. To find the x intercept, plug y=0 into 6x-6y=-6 and you get 6x-6 (0)=-6 which simplifies to 6x=-6 or x=-1.

Graphing linear equations Lesson (article) Khan Academy

WebSay you have these two equations: 3x + 2y = 6 6x + 4y = 12 then these equations would be dependent, since we can derive the second one from the first, or vice versa (by either multiplying the first one by a factor of two, or dividing the second one by a factor of two). WebTake the 2nd equation and add 3x to both sides to isolate "y". y = 3x+3 Now, substitute this value of "y" into the first equation. 3(3x+6) + 2x = 7 You can now solve for "x". Once you have the value of "x", use it to calculate the value of "y". Hope this helps. Comment back if you have questions. tipton r vi school district tipton mo
