#x# intercept: #(-9/2, 0)#
#y# intercept: #(0, -9/8)#

#x# intercepts where #y=0#
Therefore, substitute #y=0# and solve for #x#.

#0=-2x-9#
#9=-2x#
#-9/2=x#

Therefore, #x# intercept at #(-9/2, 0)#

#y# intercepts where #x=0#
Therefore, substitute #x=0# and solve for #y#.

#8y=-9#
#y=-9/8#

Therefore, #y# intercept at #(0, -9/8)#
