#y=-1/10x+3.1#

#y=mx+b# is the slope-intercept form.

Find the slope, which is

#m = (y_2-y_1)/(x_2-x_1)#

#m = (2-3)/(11-1)=-1/10#

Find #b# by substituting the #x# and #y# values into #y=mx+b #

#3=(-1/10)(1)+b#

#b=3.1#

Now you know your #m# (slope) value and #b# value. substitute back into the equation #y=mx+b# to get the equation

#y=-1/10x+3.1#
