<h2>Hello!</h2>

The answer is C. formulas

<h2>Why?</h2>

Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.

A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.

Discarding the other given options:

A. decimals: Incorrect, decimals are a type of number which is not whole numbers.

B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.

D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.

E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.

Have a nice day!

(5,60)(10,40)
slope = (40 - 60) / (10 - 5) = - 20/5 = -4

y = mx + b
slope(m) = -4
(5,60)...x = 5 and y = 60
now we sub and find b, the y int
60 = -4(5) + b
60 = -20 + b
60 + 20 = b
