Answer 1

In what form?

Answer 2

y=mx+b

Answer 3

i know y=4x

Answer 4

ok well we need to find the y intercept :) but lets just do everything at once :P
see this formula? Plug in the given info and then solve for y :)
\[\huge y-y_1=m(x-x_1)\]
where
m=slope
(x1,y1)

Answer 5

y=4x+1?

Answer 6

No try again can you show your work? So i can see where you made the mistake?
