Insufficient information given to build an equation

#color(red)("Assumption: this is for a straight line")#

Standard form:#" "y=mx+c#

Given point#->P_1->(x,y)->(1,-1)#

So #y=mx+c" "->" " -1=m(1)+c#

You may insert any values you wish into #m# or #c# to take this calculation further and determine the final equation
