2nd possible answer is the correct one; the const. of var. is 1/3.
Step-by-step explanation:
xy = 1/3 can be rewritten in inverse variation format: Divide both sides by x to isolate y. Then y = (1/3)(1/x). The constant of (inverse) variation is 1/3.
2x+y=5 To put this in slope intercept form, you simply have to get y by itself on the left side of the equation. 2x+y=5 2x+y-2x=5-2x y=-2x+5 Now, I had to switch the right side around like that, because slope intercept form is y=mx+b Because you're subtracting 2x from 5, it becomes 5 added to -2x when it's put in the correct form. y=-2x+5
