Substitute #-5# for #x# and #-4# for #y#. Solve the equation. If both sides are equal, then #(-5,-4)# is a solution for #9x-4y=-6#. If the two sides are not equal, then #(-5,-4)# is not a solution.

Explanation:

#9x-4y=-6#

#9(-5)-4(-4)=-6#

#-45+16=-6#

#-29!=-6#

#(-5,-4)# is not a solution of #9x-4y=-6#
