∙ 14y ago2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10

4(6)-10=14
6xy=13 y=13/6x You may be confused at this point because your graphing calculator graphs a line when you plug in this equation. What your calculator is doing is (13/6)x=y which is indeed a line. However, you are working on inverse variations. Plug this into your calculator y=13/(6x) How is that different? Just look at the graph.

Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.
