Answer:
Step-by-step explanation:
The line has two clear points (6,10) and (2,2)
y=mx+b
m=(y2-y1)/(x2-x1)
m=(2-10)/(2-6)=-8/-4=2 so far our line is
y=2x+b, using point (2,2) we can solve for b
2=2(2)+b
2=4+b
b=-2 so our line is
y=2x-2, and we want to know the coordinates for (4,b)
b=2(4)-2
b=8-2
b=6
Now we want to know the coordinates for (a,8)
8=2a-2
10=2a
a=5
Y = 16, -16
explanation: the absolute value bars make the expression inside positive, if they were negative to begin with. so, a negative number like -16 becomes 16, and a positive number like 16 still stays the same

Answer: 164.7 square inches</h3>
============================================
Explanation:
The area of a parallelogram is equal to the base times height
area = base*height
area = 13.5*12.2
area = 164.7
This is pretty much identical to a rectangle's area formula. This is because a rectangle is a special type of parallelogram (one with all four angles at 90 degrees).
The domain would be (negative infinity, positive infinity).
54 because 6 times 9 equals 54 so 54 divided by 6 is 9 :)) hope that helps
