Answer 1

#28
Does proportional equation have a y-intercept? No (or it's zero) because y = kx is the equation in question, k being the constant of proportionality

#28
Describe the characteristics of a proportional graph.  Straight line passing through Origin

#30
Write a fraction equal to 4/6 with a numerator of 8.  Multiply the 4/6 by (2/2) to get 8/12

#35
The population of Bay Village is 35,000 today. Every year the population Bay Village increases by 750 people.
Write a linear model that represents the population of Bay Village "x" years from today. p = 35,000 + 750x

#40
Convert each repeating decimal to a reduced fraction.
a) 0.6666... b)0.161616161616...... c)0.040404040404..... d)0.715715715715......

a) = 2/3  (everybody should already know that!

b) 16/99     c)  4/99    d)  715/999    ⇐ for .xyxyxyxy... (repeated group of 2 digits, xy/99)

for .xyzxyzxyz...(repeated group of 3 digits, xyz/99
