Terms in this set (10)
What is a system of equations?
More than one equation.
What are you finding when you solve a system of equations?
The point in which they intersect each other.
What are the three methods we have used to solve a linear system?
Graphing, Substitution and Elimination
Solve the system by Graphing: y = (-3/2)x + 5 and y = (3/2)x - 1
( 2 , 1 )
Solve the system using Substitution: x + y = 3 and y = x + 5
( -1 , 4 )
Solve the system using Substitution: 3x - 2y = 5 and x = 4y - 5
( 3 , 2 )
Solve the system using Elimination: 2x + 3y = 20 and -2x + y = 4
( 1 , 6 )
Solve the system using Elimination: 5x + 3y = -19 and 8x + 3y = -25
( -2 , -3 )
Solve the system using Elimination: 4x - 2y = 4 and 2x + y = 6
( 2 , 2 )
Solve the system using Elimination: 5x - 3y = -1 and 3x + 2y = 7
