What is the value of k in the function $f\left(x\right)=112-kx$ if $f\left(-3\right)=121$?

Determine the least Count.
Least Count:
The smallest value that a measurement tool can measure is its least count. This least count is also known as the mistake associated with the instrument's resolution.
Least count formula:
We apply the formula below to obtain the lowest count.
The least count $=$Division's magnitude divided by the number of divisions required to achieve that magnitude Meter Scale's lowest count
Considering the magnitude of $1$cm in the case of a meter scale. The total number of divisions reached is$10$.
So, the formula for calculating the least count is as follows:
$\frac{1\mathrm{cm}}{10}=0.1\mathrm{cm}\mathrm{OR}1\mathrm{mm}$
Hence, the least count on the meter scale is $0.1$cm or $1$mm.
