i had to use this equation: yy1=m(xx1)

start with y=x+c
put the point (4,2) there, and find c

oh, so u have m, right ? which is ?

i think..?

and (x1,y1) = ?

(4,2)

so it would be:
y2=1(x(4)) right?

hartnn

so now just put the values in yy1=m(xx1)

hartnn

yes, that is correct

now simplify

ohk so then i would distribute?
y2=1x+4 ?

u missed the brackets...

no cuz i multiplied (x(4)) by 1

hartnn

so u get 1(x+4) = x4

(4) = +4

ohh ohk so the answer would be y=x+2 or y=x2 ?

oh nvm

yeah thats correct
