How to solve a system of linear equations by graphing. Determine whether the lines intersect, are parallel, or are the same line

If the lines intersect, identify the point of intersection. If the lines are parallel, the system has no solution.

system of linear equations — When two or more linear equations are grouped together, they form a system of linear equations. lines — parallel, the system has no solution. consistent and inconsistent systems — Consistent system of equations is a system of equations with at least one solution; inconsistent system of equations is a system of equations with no solution. cost function — The cost function is the cost to manufacture each unit times x , the number of units manufactured, plus the fixed costs; C ( x ) = (cost per unit) x + fixed costs.
