### late scribe

Sorry everyone this is late but my computers bin messed up for about a week nowand I'm in Mr class room right now doing yesterday's blog.

So yesterday we did a lot of dictionary writing in the beginning of class.We started with an an Analytic Geometry toolkit.**The Pythagorean Theorem** = a^{2} + b^{2} = c^{2}**Slope of a line** = rise/run =y_{2} - y_{1}/x_{2} - x_{1} =y_{1} - y_{2}/x_{1} - x_{2}

(a.k.a rate of change)**Mid point of a line segment** mid = (x_{1} - x_{2}/2,y_{1} - y_{2}/2)**Distance between two points****Perpendicular (shortest) distance **line**:** Ax + By + C = 0**between a line and a point** Point: (x,y)**Equation of Lines **

-General from = Ax + By + C = 0

-Slope intercept form = y = mx + b

*point slope form = y - y_{1} = m(x - x_{1})

-if two lines are parallel

with slopes of m_{1} & m_{2} = m_{1} = m_{2}

-if two lines are Perpendicular

with slopes m_{1} & m_{2} = (m_{1})(m_{2}) = -1**Some trig we should know**

Sine Law = sinA/a = sinB/b = sinC/c

Cosine Law = a^{2} = b^{2} + c^{2} - 2bc cos**A System of liner equations**

2 lines meet at:

*One point

*All points

*No points

Then after all that we did a quiz and that was class.

And I'm doing todays blog to so ill say who's the next scribe then.
