Answer: The equation in standard form is #-9x-y-81=0#

Explanation: The equation in slope intercept form is #mx+b=y#.
#m=-9# #=># #-9x + b = y #

From the coordinates of the point #(-9,0)# we get #(-9)*(-9) + b = 0# #=># #b=-81#

So, we have the equation #-9x-81=y#, which gives us the following equation in standard form: #-9x-y-81=0#
