Question

a line passes through the point (1,2) and has a slope of 9. write an equation for this line

Answer 1

You can use point slope form.
\[y-y _{1} = m(x-x _{1})\]
Where m = slope and \[x _{1} and y _{1}\] are the coordinates of the given point.

Answer 2

ok so far i have y-2=9x-9

Answer 3

Yes. But that is not the final answer yet. You have to convert it to standard form. You know it?

Answer 4

y=9x-7

Answer 5

Got it. :)
