Solutions to such systems, if they exist, consist of ordered pairs that satisfy both equations. More general systems involving nonlinear functions are possible as well. Step 2: Write the equivalent system and graph the lines on the same set of axes. Use the graph to answer the following questions. set to another line in the xy plane. Often you'll see an equation that looks like this: y = 1/4x + 5, where 1/4 is m and 5 is b. 3-- 1, 2, 3. So we may express all the ordered pair solutions \((x, y)\) in the form \((x, mx+b)\), where \(x\) is any real number. Or it represents a pair \(\color{Cerulean}{Check:}\:\color{black}{(3,2)}\), \(\begin{array} {c|c}{Equation\:1:\:\:2x-37=0}&{Equation\:2\:\:-4x+2y=-8}\\{2(\color{OliveGreen}{3}\color{black}{)-3(}\color{OliveGreen}{2}\color{black}{)=0}}&{-4(\color{OliveGreen}{3}\color{black}{)+2(}\color{OliveGreen}{2}\color{black}{)=-8}}\\{6-6=0}&{-12+4=-8}\\{0=0\quad\color{Cerulean}{\checkmark}}&{-8=-8\quad\color{Cerulean}{\checkmark}} \end{array}\), Determine whether \((1, 0)\) is a solution to the system. If we graph both of the lines on the same set of axes, then we can see that the point of intersection is indeed \((3, 2)\), the solution to the system. System of two linear equations in two variables. Please note that the symbol must be entered in calculator as >= (in form of two characters greater and equal to), and the symbol - as <=.
