find

#

the equation of the line AB

#

because its asking about the line AB right

#

and whether point C lies on it

#

dou know how to find the equation of theline AB?

#

why did u find the gradient of bc?

#

once u find equation of line AB u would need to check if C lies on it correct?

#

to check if a point lies on a line you would input the x and y values of that point into the equation of the line and see if it fits

#

so first step is work out equation of line

#

oh okayy dont owrry

#

yess so u got the gradient 2 for AB

#

now work out the line AB

#

yess

#

now work out the line AB and lmkk

#

np

#

yes exactly

#

and if u input the x=19 and get -23 as ur y value

#

then u know that point C lies on the line

#

okay soo

#

u would present it likethis

#

let me do it real quick

#

this is the solution

#

u might need to retry working out the gradient

#

it can be tricky

#

cus mistakes are easily made

#

ahh i see

#

i did the same thing first time

#

dont worry bout it remember to check

#

no problem

#

if u need help again let me know
