In this case our y-intercept, #b#, is -3 and our slope, #m#, is #-7/9#

Explanation:

One method we could use to find both is to rewrite the equation in slope intercept form, #y=mx+b#, where #m# is the slope, and #b# is the #y#-intercept.

#−7x−9y=27#
#-9y=7x+27#
#y=-7/9x-3#

In this case our y-intercept, #b#, is -3 and our slope, #m#, is #-7/9#! :D
