The boundary of a linear inequality is 3x+2y= 12. The coordinates (2, 3) satisfies the inequality, so
A. a dashed line will represent the boundary, but the solution region is unknown
B. a solid line will represent the boundary, but the solution region is unknown
C. the boundary line type is unknown, but the solution region is above the
boundary
D. the boundary line type is unknown, but the solution region is below the
boundary

  2. 3*2 + 2*3 = 12 which lies on the line.
    so the boundary is a solid line.
    So B
