8 is in the hundreds place
1 is in the tens place
7 is in ones or units place
Circumference - 2 x PI x radius
Circumference - 2 x 3.14 x 18 = 113.04 units
------------------------------------------------------
Option A
------------------------------------------------------
------------------------------------------------------
Check if slope = 2
------------------------------------------------------
y + 2 = 2(x + 3)
y + 1 = 2x + 6
y = 2x + 6 - 1
y = 2x + 5
Slope = 2
Answer: Yes, Slope is 2
------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
When x = 2
y = 2(2) + 5
y = 9
Answer: No, it does not passed through (2, 3)
------------------------------------------------------
Option B
------------------------------------------------------
------------------------------------------------------
Check if Slope is 2
------------------------------------------------------
y - 3 = 2(x - 2)
y - 3 = 2x - 4
y = 2x - 4 + 3
y = 2x - 1
Slope = 2
Ans : Yes, slope is 2.
------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
when x = 2
y = 2(2) - 1
y = 4 - 1
y = 3
Answer : Yes, it passed through (2, 3)
------------------------------------------------------
Answer: (B) <span>y – 3 = 2(x – 2)

Juan has $20 and Julio has $40
Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )
