1. Create your equation using the information in the directions. State your equation.
2. Complete the table below. Show your work.
3.    Table of Ordered Pairs    x      -2     0     2 , y=?
4. State in what quadrant or on what axis each ordered pair from part b is located.
5. Graph your equation and capture a picture of the graph to post to the discussion board. You may use your graphing calculator emulator software or take a digital picture of your graphing calculator screen. The image should be visible in the textbox where you are typing your work. Do not attach it as a file. (Please follow the instructions above for inserting an image into your post.)
6. What window did you use to graph your equation?

Solve for k in the equation -8 + 44 = -20 + 80 and explain each step.

Draw Dienes block to show how to find the solution to:

a) 56 + 48

b) 90 − 36

Note vector notation: (vector 1;vector 2)

Select the correct answer:

k(k-1) • • • (k-r)(m+1)m• • • 3• 2

_________________________ =

p(p-1)• • • (p-m)(r+1)r• • • 3• 2• 

a) (k;r) / (p+1 ; m)

b) (p;r) / (k+1 ; m)

c) (k;r) / (p ; m + 1)

d) (k;r) / (m+1 ; p)

e) (k; r +1) / (p ; m)

f) (k; r + 1) / (p ; m+1)
