Slope is # -9#, y-intercept is # 0 # and x-intercept is # 0 #.

Explanation:

#y= -9x or y = -9x +0# ,

Comparing with general straight line equation #y=mx+c#
where #m# is slope and #c# is y-intercept, we get here slope as

# m =-9 # and y-intercept as #c=0# So y-intercept is at #0,0#

To find x-intercept putting #y=0# in the equation we find #x=0# So x-intercept is also at #0,0# graph{-9x [-40, 40, -20, 20]} [Ans]
