The endpoints of bar(AB) have coordinates are A(9, 8) and B(-1, -2), so the midpoint is simply the average of x- component of both coordinates and the average of y- component of both coordinates.
A=(x₁, y₁)=(9, 8)
B=(x₂, y₂)=(-1, -2)
The midpoint formula is given below;
is the midpoint of bar(AB).
70 because 180-110=70 sorry if it’s not correct

Answer:
Linear association and positive correlation, or a.
Step-by-step explanation:
The dots appear to go up, giving the positive appearance, and the dots are in a linear shape, hence the linear association.
Answer:
B) x+y=120; 12x+20y=1720
Step-by-step explanation:
If variables are defined as ...
x = number of student tickets sold
y = number of adult tickets sold
then the problem statement can be modeled by ...
x + y = 120 . . . . . . the total number of tickets sold is 120
12x + 20y = 1720 . . . . . the total collected from ticket sales was $1720
___
Total revenue is the sum of the revenues from sales of each ticket type. The revenue from a given ticket type is the product of that ticket price and the number sold.
