See a solution process below:

The slope-intercept form of a linear equation is: #y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

Substituting the slope and #y#-intercept from the problem gives:

#y = color(red)(1)x + color(blue)(-9)#

#y = color(red)(1)x - color(blue)(9)#

Or

#y = x - color(blue)(9)#
