Here's the graph:

anonymous · Answer

Ok, so your slope is positive and then you know when x is zero, y is -4, and when y is zero x is 6. So now you can just plug those in and see which works.

anonymous · Answer

For example 
$$2(0)+ 6y = 12, y = 2$$

anonymous · Answer

so option a isn't it.

anonymous · Answer

Oh! So it's B right? :D

anonymous · Answer

That is correct! Stay winning!

anonymous · Answer

Yuusss! Omg thankyouuu :D Forgot x or y had to be zero.. Merp:P

anonymous · Answer

np, good luck on the rest of them.

GREAT! However, there is a better way to handle that type of problem instead of going by trial and error.

anonymous · Answer

Oh really? What's your way?:P

nincompoop · Answer

solve for the equation of the line given two coordinates.
