ok i have to plot a graph for my kinetics

Question

our teacher said in the end it'd the end the graph would give me numbers like this,

y = 1.3x10^2x-11.2
r^2 = 1
but when i plot it, i get weird numbers. am i supposed to plot exponents as i wrote them below? also does Lnr become positive or negative when plotted?

my numbers are:
X value:
3.50X10^-3

3.14X10^-3

3.28X10^-3

y value:
-11.8 (this number is LnR, i think the teacher said this number becomes positive when plotted? )

-11.3

-9.75
