Answer:
The equation of a line y = ax + b passes point (-8, -33) and point (0, -1) can be formulated by:
(Note: we do not need all of 4 points, 2 points are enough)
-33 = a x (-8) + b
-1 = a x 0 + b
From 2nd equation, we have:
b = -1
From 1st equation, we have:
b - 8 x a = -33
=> -1 - 8 x a = -33
=> 8 x a = 32
=> a = 4
=> The equation of line: y = 4a - 1

Answer: 7/12!
Step-by-step explanation: 7/9 times 21/28 = 147/252. But you have to reduce it (simplify it) by dividing both the numerator and denominator by the greatest common factor and you get 7/12! Hope this helped.
So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.
The area of the rug is 354.34 square inches.
Answer:
9. y = 8
10. n = 21
11. 44 = v
12. c = 35
Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35
