I am trying to find the equation to m= 8(3,2)This is what I did and then I get stuck, sorry

m=8(3,2)
y=2(8)(x-3)
y=2x-? this is where I get stuck -24 or -5

Your first line was probably

y-2 = 8(x-3)
then
y = 8x - 24 + 2
y = 8x - 22

(I don't like your notation of m=8(3,2)
I hope nobody teaches you that )
