So my teacher is making me solve systems by graphing. One of them was 3x + y = 6 and 2x + 3y = 13 . I converted both of them into slope intercept form and got y = 3x + 6 and y = 2/3x + 13/3 . The thing is I don't know how to graph a fraction ?!?!?! And if I turn that fraction into a decimal, I also won't know how to graph the decimal. Help? (:

OMG SOMEONE HELP PLEASE !!!! :/ I'm desperate

Okay so no one wants to help... alright _

Solve without graphing first so that you know what x and y equal.
Then pick three points for each to graph.
3x + y = 6
x = 1, y = 3
x = 2, y = 0
x = 3, y = 3
2x + 3y = 13
x = 1, y = 11/3 = 3.67 (3.67 is a little more than 3 1/2)
x = 2, y = 3
x = 3, y = 7/3 = 2.34 (2.34 is a little more than 2 1/4).
Since you have already solved without graphing, and know the solution for x and y, this should help to see where the lines should intersect.
The solution for this system is,
x = 5/7 = 0.71 approx. which is about 3/4
y = 27/7 = 3 6/7 approx. which is about
4)
Good luck :)
