y=6x-41 i believe because if you bring the -6x over it is in slope intercept all you have to do is plug in the points to get the y intercept
In this question, the given value is

And we have to find the value of sin theta and tan theta where theta is in first quadrant .
And in first quadrant, all are positive .
Now we use the formula, which is

And tan theta is the ratio of sin theta and cos theta, that is

So the correct option is B .
A=5
I've had this question recently, hope it helps. :)
FYI, If you have trouble with algebraic questions such as these, I recommend a website called MathPapa.com, It's a user-friendly "calculator", but it takes you step by step through each problem so It's like your own free tutor. :) It's helped me learn a lot and now i'm doing much better in math!
