Pre-Algebra: Chapter 8-8
Systems of Equations
Take 2 linear equations and graph them (with at least 2 points for each linear equation) and where they intersect is a “SOLUTION” to BOTH equations. Pretty simple to do, but it can be time consuming in that you have to have graph paper and a ruler and some time ….
It helps to use the x and y intercepts. Remember, setting x = 0 lets you solve for the y-intercept. Setting y = 0, lets you solve for the x-intercept!
