Scribe Post for 3/12/08

Scribe of the Day.... Lena

Today is March 12, 2008
And in math class we learn about…



Explicit Formula's


Explicit Formula- Operation with linear equation involves multiplication/division or addition and subtraction


Today's Example:

0,3
1,5
2,7
3,9
4,11
x, 2x+3

The explicit Formula is- y=2x+3




TODAY'S TERM OF THE DAY

SLOPE


Slope= Rise/Run it represents the ratio of going from one point to the next.

Slope= y2-y1/x2-x1

Looks confusing right.... Well it's not

Just look at it this way...

0,3 is the starting point right

3 is your Y intercept

If X is Zero you can find your Y intercept by looking at the number

Slope=Intercept= intercept form


EASIEST WAY TO KNOW!!!!


y=mx+b

M=slope
B=y-intercept
Y=Intercept from


Here how we would graph it
