6. Gravetter/Wallnau/Forzano, Essentials - Chapter 1- End-of-chapter question 30 For the following set of scores, find the value of each expression:
X
6
1
4
5
2
∑X² =
(∑X)² =
∑(X – 3) =
∑(X – 3)² =

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

51840000 cm 2

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
