Answer: y + 3 = 4 (x +1 )
Step-by-step explanation:
The eqution of a line in point- slope form is given as :
= m(
)
Where m is the slope and ( ,
) is the given point
substituting the values into the formula , we have:
y - (-3) = 4 ( x - {-1) )
y + 3 = 4 ( x + 1)
This is the equation of the line in point-slope form.
Answer:
A proof can be as follows:
Step-by-step explanation:
Let be a set of
integers. By the division algorithm the possible remainders when we divide by
are
. Then, each integer
can be written as:
Observe that the set of remainders has
elements and each element has
possible values. By the Pigenhole principle at least two remainders have the same value. Suppose that this two elements are
. Then,
Where . Then,
. Then we have that
divides
.
