Solving systems of linear equations by graphing and substitution.
|Is (4,1) a solution for: x + y = 5 x + 4y = 8||Yes|
|How do you find a solution to a system of linear equations by graphing?||Graph the two equations and find the point where they intersect.|
|If you simplify 5(x + 1) + 6x - 3, what does it come out to be?||11x - 2|
|Are x = 1 and y = 1 parallel or intersecting lines?||Intersecting.|
|To solve by substitution, what is the first step you must take?||Find x or y for one of the equations.|
|If x is a single real number, what can you know about what the graph will look like?||It will be a single vertical line crossing the real number on the x-axis.|
