Why are percents rational numbers

By definition, we have:

Rational number is any number that can be represented as the quotient of two whole numbers or, more precisely, an integer and a positive natural.

For the case of percentages, we must always divide by 100 to convert it into a number.

For example, 50% written as a number is:

50% = 50/100

Percentages are rational numbers because they must always be divided by 100 to become a number.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
