Question

A. Determine if the given points is a solution of the given system of linear equations.

1. ( 3, 3 )

• y = 3x + 6

• y = -2x + 9

 

2. ( 8, 13 )

• y = 2x - 3

• y = x + 5

 

3. ( -1, 0 )

• 3x + 3 = 2y

• 4 - 5y = -4x

 

B. Without graphing, identify the kind of system, and state whether the system of linear equations has an intersecting graph (has one solution), a coinciding graph (has infinitely many solutions), or a parallel graph ( has no solution).

1. x + y = 2

    x + y = 4

 

2. x - y = 3

   4x - 4y = 12

 

3. 3x + 7 = -5y

   5y - 7 = -3x

 

4. 2y = 4x - 6

   3x - y = 2
