Solving Systems Of Equations By Graphing Worksheet With Answers Solve each system by graphing y 1 2x 4 2x 4y 16 Answer If you write the second equation in Exercise 5 1 22 in slope intercept form you may recognize that the equations have the same slope and same y intercept When we graphed the second line in the last example we drew it right over the first line
Without graphing determine the number of solutions and then classify the system of equations y 3x 1 6x 2y 12 We will compare the slopes and intercepts of the two lines y 3 x 1 6 x 2 y 12 The first equation is already in slope intercept form Write the second equation in slope intercept form Answer In Exercise 5 2 7 it was easiest to solve for y in the first equation because it had a coefficient of 1 In Exercise 5 2 10 it will be easier to solve for x Exercise 5 2 10 Solve the system by substitution x 2y 2 3x 2y 34 Answer Solve for x Substitute into the other equation

3 1 Solving Systems of Equations by Graphing 4 Write your questions and thoughts here 6 y 2x 5 Sketch the graph below y 2x 1 Step 1 Solve both equations for y Step 2 Enter both equations into the calculator in y Step 3 Press zoom 6 Step 4 Press the 2nd Key and then press Calc Step 5 Press 5 Step 6 25 Write a system of equations with the solution Solve each system by elimination Many answers Ex x y 1 2 x y 5 Create your own worksheets like this one with Infinite Algebra 2 Free trial available at KutaSoftware
Let s do this with the following systems of equations y 1 2 x 3 y x 1 First let s graph the first equation y 1 2 x 3 Notice that the equation is already in y intercept form so we can graph it by starting at the y intercept of 3 and then going up 1 and to the right 2 from there Next let s graph the second equation y x Slope intercept form is easy though The equation for slope intercept form is y mx b In this equation m is the slope and b is the y intercept To graph a line from a slope intercept equation take the value of the slope and put it over 1 For example if the slope was 5 the slope would be 5 1

This section we solve systems of linear equations in two variables and use systems to solve problems Solving a System by Graphing Because the graph of each linear equation is a line points that satisfy both equations lie on both lines For some systems these points can be found by graphing EXAMPLE 1 A system with only one solution Solve the This is called solving by graphing and is a valid approach for linear equations with relatively simple slope and y intercept values The graphing systems of equations worksheets on this page fit this criteria and they are good practice for building a visual intuition of the solution process In practice it the linear equations in a system
