### Scribe for Tuesday is: "lan"

**Horizontal and Vertical Lines!**

Hello everyone! I hope you're having a good weekend!

The first thing we did today was writing our Muddiest Point in one minute! Well, that was quick!

After that Mr. K tried to explain to us the question that he gave us a day before which was:

*2 perpendicular lines that have intercepts at point (9, 2) and the x-intercept of line 2 is twice the x-intercept of line 1.*He start it like this:

M -1/m

y-y1=m(x-x1) y-y1=m(x-x1)

y-2=m(x-9m) y-2=-1/m(x-9)

y-2=mx-9m y-2=-1/mx+9/m

y=mx-9m+2 y=-1/mx+9/m+2

0=mx-9m+2 0=-2x/m+9/m+2

0=m(x-9)+2 0=1/m(-2x+9)+2

-2=m(x-9)

......And he went on and on and when he stopped he said that he couldn't do it with us looking at him<>

Ok, back to out subject;

we put some info. about the

**Horizontal and Vertical lines**in our dictionaries.Note that the

**Horizontal**lines have a slope equal to zero (0), and the equation is written as**: Y=B**and**B**is the*y-intercept.**Example: a horizontal line with y-intercept of -2 has an equation of:*

**y=-2**And also, all vertical lines DO NOT have there slope defined, so we say:"

**The slope is undefined.**" The equation is written as:**X=K**( K is the*x-intercept*.)*Example: a vertical line with x-intercept of 7 has equation:*

**x=7**

As you can see i just copy down what we wrote [-( .

well, i can't explain so good and i might've missed some important points so i just copy down the stuff.

you know who the scribe is.... "lan"

See you Tuesday!
