I will give you statrak five seven scumbria, and statrak tec 9 isaac (I know its jack shit)
The question is.
The Point P lies on the line joining a (-2,3) and B (10,19) such that AP:PB=1:3
Show that the x coordinate of p is 1 and fine the y coordinate of p

yes

fuck graphing problems, had the most problems with those type of math questions and math is usually simple for me.

I am outside every day for many hours (Because one of my favorite things to do is BMX)

Expected from the cool kid in class

This is one of those problems that would take 3 pieces of paper to complete. Should I really do this?

This is the answer

The Point P lies on the line joining a (-2,3) and B (10,19) such that AP:PB=1:3
1. Show that the x coordinate of p is 1.
You know starting point A(-2,3) and ending point B(10,19) and the ratio of P which is a total of 4 parts (1 part to A and 3 to B).
Only considering X-axis the total distance is 12 (-2 to 10). 12 / 4 parts is 3. so P in x terms of X-axis is 1 part from A. -2 + 3 = 1.
2. find the y coordinate of p:
Use the 2 points to construct a line: y = ax + b a = slope (y2 - y1) / (x2 - x1) = 16 / 12 = 4/3
Use 1 valid point to find b. I use B: 19 = 4/3 * 10 + b -> b = 5(2/3). so the line is y = 4/3x + 5(2/3)
Insert x = 1 you get: y = 4/3 + 5(2/3) = 7.
Problem solved.
EDIT: Only did it for the skins (where are they?!)

Great approach to the first question. My method would probably take 6 hours to write down.

you have to show, not prove.
question is simple.

I know. I first expressed the coordinates of P in terms of p in x and p filled in the constructed slope formula, then express the distances in terms of p and then solve that for p. I haven't had any Geometry this year so that probably explains this terrible approach.

if you dont consider teh relation of 1:3 you will end up with an equation saying P = P.

youre an absolute genius, tradelink?

y=7
If you take the difference between x_B and x_A, you get 10-(-2)=12. The ratio is 1:3, so x_P is
x_A+1/4(x_B-x_A)=-2+1/4*12=-2+3=1.

Cant do english maths or german in general

You an use the section formula.
Let A(x1,y1) = A(-2,3)
Let B(x2,y2) = B(10,19)
Let given ratio 1:3 = m:n
Then P(x,y) = {(mx2±nx1)/(m±n) , (my2±ny1)/(m±1)}
Putting in the values of m,n,x1,y1,x2,y2
You get P(x,y) = P(1,7)
Look up the section formula on Google if u need the proof.
