# y intercept

I am trying to solve the following problem
A line contains the point (1,3) and has the same y intercept as y-5+2(x-1). What would the y intercept be here?

Well, I used the formula y-y1+m(x-x1) with the ones being below the line.

So, y-3+m(x-1)...but I need to know the "m" or y intercept.

That is not an equation of a line - be a little more careful

Again the same mistake....
Just simplify your equation - then write it in the form of:

y = mx + b

then 'b' is the y-intercept.

or

you can solve for 'y' at x = 0 --- that value of y will be the y-intercept.

First of all, I looked back at my first post and may have made a mistake.

The formula was y-5=2(x-1)

Does this make a difference?

and would y be 2 ?

Yes, I did...and I am confused!

Do I use the points (1,3) with 3 being the b?

Hmmm...may as well stop here hmwin; you obviously need classroom help.
