Solve systems of linear equations by graphing
WebJul 23, 2024 · Step I: Take a point M on the y-axis in the positive direction of the y-axis such that OM = 5. Step II: Through M draw a line MN parallel to the x-axis. Step III: Draw a line MP through M such that the line makes an angle 60° with MN (positive direction of the x-axis). This is the required graph of y = √3x + 5. WebYou can solve systems of linear equations by graphing, the elimination method, or by substitution. To solve by graphing, graph both of the linear equations in the system. The solution to the system is the point of intersection of the two lines. It’s best to use the graphing approach when you are given two lines in slope-intercept form.
