Question

Assignment:

A Motto for Algebra.  This Question is a bit different.  A little fun for the last team assignment and a mini-review.  Using code template, find the motto for this class. Find the answer using questions below. Wherever a number appears in the table below, put in the letter you've decoded from the number.

Coding Table:

Letter     Number    Map

A		3-4(2-1)=?
		For y = -2x - 6
E		slope
I		y-intercept
		Solve this system of equations: x+y=5 and 3x-5y= -9
T		X=?
S		Y = ?
R		For x/3-y/6=5, what is Lowes5t Common Multiple, that is, what do you multiply all terms by to eliminate the denominators?
O		What is the reciprocal of 1/7?
L		What is opposite of 4
N	O	If the slope of this line is undefined, what is x? m = 2/x
G		What is y for this system: 4x-4y= 6 and -2x+4y= 5
