Solve and graph linear equations
WebSep 5, 2024 · The linear equations graphed above were solved for y. If the equation is not stated in terms of y, it is best to first solve the equation for y. If there is no y in the equation, then solve the equation for x. Example. Graph the linear equation y + 3x = 5. Solution. Solve y + 3x = 5 for y y + 3x − 3x = 5 − 3x y = 5 − 3x. WebSolve by Graphing One method to find the solution of a system of linear equations is to graph each equation on a coordinate plane and to determine the point of intersection (if it exists). The drawback of this method is that it is not very accurate in most cases, but does give a general location of the point of intersection.
