Here are the steps to solve these problems:
1. Find the slopes of the two lines:
m1 = (8-2)/(5--2) = 6/3 = 2 (slope of r)
m2 = (7-0)/(-8--2) = 7/-6 = -1 (slope of s)
The slopes are negative reciprocals, so r ⊥ s.
2. The slopes are m1 = 2 and m2 = -1/2. Since m1 × m2 = -1, the lines are perpendicular.
3. The given line has slope 3. The perpendicular line will have slope -1/3. Plug into the point-slope form

I didn't make this powerpoint, this is from my IB Biology teacher but it's one of the only topics I actually really enjoyed sooo I'm putting it up, ^_^
Frau Freud by Carol Ann Duffy & Sigmund FreudAlice Palmer
Please read Frau Freud by Carol Ann Duffy. She's a brilliant poet, this poem is from an anthology where she writes from the perspective of the female counterparts of famous male figures - in this case Freud. Have we ever wondered what it would actually be like to have to be the wife of such an influential figure? Especially Freud? This is from a presentation I did on him to give some context to the poem, enjoy!
An old powerpoint from highschool for higher level IB engilsh. A doll's house is one of my favorite plays so if you're trying to cheat your way from reading it I'll be mad. Read it, it's awesome. And yes, the characters are excruciatingly whiny and obnoxious and all remind me of my sister. Hope it helps!
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
3. Gradient measures the steepness of a slope.
• Step 1: Measure the rise (difference in height
between 2 points)
• Step 2 : Measure the run (the distance
between 2 points). Make sure that you
convert the scale into metres
• Both the rise and run need to be expressed in
metres.
4.
5.
6.
7.
8. • Say the rise is 42 metres and the run is 600
metres.
• 42(rise)/600(run) - Formula (divide the top by
itself and the bottom by the top)
• Divide 42 by itself = 1
• Divide 600 by 42 = 14.3
9. • The answer can be expressed in three ways:
• a) As a statement 1 in 14.3
• b) As a ratio 1: 14.3
• c) As a representative fraction 1/14.3

11. A theorem to find the length of sides of right triangles
• What do the variables stand for?
a = the Y, vertical side of the triangle
b = the X, horizontal side of the triangle
c = the hypotenuse of the triangle
• What type of triangle do we use the theorem for?
-Right angled triangles.
12. • Draw a right triangle with two sides labeled with numbers

9+16=x2
x=25 4
(The opposite of x2 is )
X=5
13. The distance formula is a mathematical formula used to
measure how far apart two points are from one
another.
• What steps do you follow to use the distance
formula?
Label the points.
Put them in the distance formula.
Do the math.
(x2 – x1)2 + (y2 – y1)2
14. • List two points

15. •The midpoint of a segment is the POINT M.
•The midpoint is a dot with a coordinate (x, y).
•M = ( [x₁ + x₂]/2, [y₁ + y₂]/2 )
•Take the x coordinates, add, divide by 2 = new x
coordinate.
•Take the y coordinates, add, divide by 2 = new y
coordinate.
•M = ( x, y )

19. Perpendicular Lines Postulate:
• Two non-vertical lines are perpendicular if and only
if the product of their slopes is -1.
Vertical and horizontal lines are perpendicular.
• l1⊥l2 if and only if
m1∙m2 = -1
• That is, m2 = -1/m1,
The slopes are
negative reciprocals
of each other.
20. Theorem: Perpendicular to Parallel Lines:
• In a plane, if a line is perpendicular to
one of two parallel lines, then it is
perpendicular to the other.
and
Then
21. Theorem: Two Perpendiculars:
• If two coplanar lines are each
perpendicular to the same line, then
they are parallel to each other.
22.
23. If 2 perpendicular lines have gradients m1
and m2 then m2 is the negative reciprocal
of m1.
E.g. If line a has a gradient of 3 then line b
must have a gradient of -3 if both lines are
perpendicular to each other.
