One way is by intuition
lets list all the perfect squares
1
4
9
16
25
36
49
etc
if we list their differences, we notice a pattern
4-1=3
9-4=5
16-9=7
25-16=9
36-25=11
49-36=13
etc
we notice that the difference between 2 consecutive squares is always an odd number, also the odd numbers go up
before, I said that it was false because we can't get 1, but we can do 1²-0²=1
to get negatives, reverse it
-1=0²-1²
so we can see that we can get all the odd numbers
another way I saw in another answer by Syed514 in this question:
brainly.com/question/2284978anyway
so what syed did was
any odd number can be written as 2n-1 where n is an integer
odd=2n-1
odd=0+2n1
odd=n²-n²+2n-1
odd=n²-(n²-2n+1)
odd=n²-(n-1)²
we can now see that any odd number can be written as a difference of 2 squares
we also have shown that any odd number can be written as the difference of 2 consecutive square numbers

Answer:
Step-by-step explanation:
an equation perpendicular to the equation given will have a slope of -1, because a perpendicular slope is opposite and reciprical. if it goes through the point 4,-1 and has a slope of -1, the y intercept has to be 3. y = -x + 3
parallel lines have to have the same slope of 3.
