Use divisibility rules to simplify the fraction completely. Divisibility Rules:
63
A number is divisible by...
111
2, if the number is even
3. if the sum of the digits is divisible by 3,
4. If the last two digits are divisible by 4,
5, if the final digit is 5 or 0.
6, if the number is divisible by both 2 and 3.
7, if when you double the final digit then subtract it from the number
made by the other digits, the result is divisible by 7.
8, if the final three digits are divisible by 8
9, if the sum of the digits is divisible by 9,

for the points! : )

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?
