Question 2
2.
Review Lesson 2-2: Tag each equation based on whether y varies directly with x. If it does, also tag it with its constant of variation.
y varies directly with x
y does NOT vary directly with x
constant of variation: -5
constant of variation: 3
constant of variation: 100
y = x + 3
y = 100x
-5 = y + x
5x + y = 0
