Answer: n2 + 1
Step-by-step explanation: Make sure the 2 in the n is small. When a number is squared increased by 1 that means;
a number = a variable, I used n.
squared = In mathematics, a square is the result of multiplying a number by itself.
increased by 1, is just simply adding 1 to the squared number.

The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -3), we can say (x1, y1) = (-1, -3)
So ,
Since the second point is (-4, -8), we can also say (x2, y2) = (-4, -8)
So ,
Put this all together to get: , , , and </span>

Answer:
In some schools yes but it depends is it a required class? if so then you'd have to retake it.
x-3y= -3x +3y=9
collect like terms
-3x will go to x and it will turn to
x+3x And -3y will go to +3y and it will turn to
×+3x=+3y+3y=9
solving time.
x+3x is 4x
3y +3y =6y
4x+6y =9
remove the 4x for now.
6y divided by 9.
3 in 6 is 2 and 3 in 9 is 3.
therefore 4x =2=9
4/2=2
2x=9.
4and half is the answer
