WebThe solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently. In this example, the ordered pair (4,7) ( 4, 7) is the solution to the system of linear equations. We can verify the solution by substituting the values into each equation to see if the ordered pair satisfies both equations. Webthat is, “two line equations in and ”, then . . . If the 1. lines intersect: we have one ordered pair that lies on both lines 2. lines are parallel: no ordered pairs lie on both lines 3. lines coincide: infinitely many ordered pairs lie on both lines Ordered pairs that work in both equations are called solutions to the system of equations. WebSep 27, 2024 · A linear equation is an equation with two variables whose ordered pairs graph as a straight line.
