@wicked compass you there

[wicked compass]

YH

yh*

[woven garden]

i can help you with the question

which part

[wicked compass]

ok i calculated the gradiant for PQ

A pls

and probs b but i havent started yet

[woven garden]

now use the negative reciprocal

you will get -3/2

[wicked compass]

yh

[woven garden]

then you sub (9,10) to get c

once you have the line equation

solve for a

4=-3/2(x) +47/2

[wicked compass]

sub 9,10 into what?

[woven garden]

the equation of line that we found

-3/2x +47/2

you know how you calculated the gradient of pq

[wicked compass]

im sorry where did we get 47/2 im a bit slow

i havent done circles in a while

[woven garden]

ok, because we got the negative reciprocal

we are gonna use the (9,10) to find c

y=mx+c

we know our m

and our x and y

[loud tulip]

y- y1 = m(x-x1)

[wicked compass]

then?

[woven garden]

use the (9,10) to prove that a=13

[wicked compass]

ohhh

i see

im so slow

thanks

[woven garden]

you want help with part b

[wicked compass]

lrt me try it and ill @ if i need help?
