Question

how do I solve
m=8/9,(2,-1)

Answer 1

solve what exactly?

Answer 2

the full question Find an equation of the line having the given slope and containing the given point.

m=8/9,(2,-1) I don't know how to type the fraction 8/9 but that's what it is.

Answer 3

okay, you know that m=slope, right?

and the format for the point given is (x,y)

so just plug those into y=mx+b

Answer 4

and find b

Answer 5

ok this is how I was doing it. Idk if I am setting this up right. If so this is where I get stuck.

y-(-1)=(8/9) (x-2)
y+1=8/9x 2/1= 16/9
this is where I get stuck how do I proceed

Answer 6

you're not plugging the values in correctly,

it's y=m*x+b

m=8/9, (2,-1)
(x,y)

-1=(8/9)(2)+b

now just solve for b

Answer 7

thank you

Answer 8

no problem !
