1) b. There are 10 100's in 1,000
2) c. This is what it is written in words
--------------------------
Slope :
--------------------------
Slope = 5/8
--------------------------
Equation:
--------------------------
y = 5/8 x + b
--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3
--------------------------
Equation :
--------------------------
y = 5/8x - 3
-----------------------------------------------------------------
Answer: y = 5/8 x - 3
-----------------------------------------------------------------

Answer:
C
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
You can write it as...

Carry the 4x

Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have

Therefore our answer is -1
