Oh, dude, okay, so like, proportional relationships are when two quantities change at the same rate, you know, like if you double one, the other doubles too. Non-proportional relationships are when they don't change at the same rate, so like, one could be going up while the other is just chilling. It's all about that balance, man.
3-6 is an expression. It is neither a proportional nor a non-proportional relationship.
For proportional relationships the ratio is a constant.
They aren't.
For each of the following relationships, graph the proportional relationship between the two quantities, write the equation representing the relationship, and describe how the unit rate, or slope is represented on the graph.
A relationship that occurs when variable quantities are directly proportional to one another. A linear relationship can be represented on a graph as a STRAIGHT LINE. Linear relationships always follow the formula: y=mx+b where y is the value of the y-coordinate, where my is the slope of the line, where x is the value of the x-coordinate, and b is the y-intercept
A is proportional to C4.
