Solving Systems by Different Methods
2
System of Equations
is a set of 2 more equations of a line.
3
Point of Intersection
Is where to lines cross. This is the solution to a system of equations.
4
Solutions to a System
1 Solution = has a point of intersection.
No Solution = parallel lines, they do not intersect.
Infinite Many Solutions = lines are the same, they intersect at all points.
5
Picking Which Way to Solve a System.
Graphing = they both must be in Slope-Intercept Form (y=mx + b).
Substitution = Looking for one variable to be isolated in one equations.
Elimination = want x and y on the same side in both equations.
