Direct link to Seed Something's post *When y equals one value, Posted 10 years ago. Direct link to Krishna Shinde's post If you have never heard o, Posted 7 years ago. The graphing method is not the most accurate method for determining solutions, particularly when the solutions have coordinates that are not integers. Is there a different problem you would like further assistance with? If you're struggling to clear up a math equation, try breaking it down into smaller, more manageable pieces. Determination of special cases such as unbounded, unbounded or infeasible solutions. in the xy plane, this constrained our solution A -1 *B method of solving a system of equations x and y pairs that satisfy this equation. Substitute the expression from step 1 into the other equation. Plug the value in step 2 into the first equation and solve. Mathematics is a way of dealing with tasks that involves numbers and equations. When graphing linear equations, it helps if the equations are written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. at 3, right there.
