Slope = -3
#x_("intercept") =0#
#y_("intercept")=0#

Consider the standard form of #y=mx+c#

This is the equation of a straight line that passes through the origin.

In your case #c=0# so #" "y_("intercept")=c=0#

#x_("intercept") # occurs at #y=0#

So as #0=mx# it means that as #m!=0" then "x=0#

#x_("intercept") =0

The gradient is m =-3
