#y = -15/11x - 9#

To write this equation we will use the slope-intercept formula.

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.

In this problem we are give:

#color(red)(m) = -15/11#

and

#color(blue)(b) = -9#

Substituting these into the formula gives:

#y = color(red)(-15/11)x + color(blue)(-9)#

#y = color(red)(-15/11)x - color(blue)(9)#
