Can anyone help?
I have the following equation that is in point slope form: $y-3 = {\textstyle{3\over11}}(x-4).$ I now need to get this equation into THIS form: $3x-11y = -21.$
The first step is to do the multiplication on the right hand side to give this answer:
$\ \ \ \ y-3 = {3\over11}x - ({3\over11} \cdot 4)$.
Then to get the $y$ alone on the left, move the $3$ over giving:
$\ \ \ \ y = {3\over11}x - ({3\over11}\cdot 4) - 3$.
Then do the calculation on the right to give:
$\ \ \ \ y = {3\over11}x + 1.90909090$.
But how do I get rid of the fraction $3/11$? Plus the values don't seem like they will add up? Seems like a primary school question but I can't figure this out. Any help would be appreciated.
In case your wondering, I have taken this from a tutorial found here (in step 3 of the tutorial).
PS: sorry if tag is wrong but I did not know what to add it under
