Problem 4

ForLesson 8: Comparing Relationships with Equations

Decide whether or not each equation represents a proportional relationship.

Volume measured in cups ($c$) vs. the same volume measured in ounces ($z$): $c = \frac18 z$
Area of a square ($A$) vs. the side length of the square ($s$): $A = s^2$
Perimeter of an equilateral triangle ($P$) vs. the side length of the triangle ($s$): $3s = P$
Length ($L$) vs. width ($w$) for a rectangle whose area is 60 square units: $L = \frac{60}{w}$
