Homework help for #4a

Read the following from your problem set lesson summary for help with 4a.

Lesson Summary:
The points (0,0) and (1, r), where r is the unit rate, will always fall on the line representing two quantities that are proportional to each other.

 The unit rate r in the point (1, r) represents the amount of vertical increase for every horizontal increase of 1 unit on the graph.

 The point (0,0) indicates that when there is zero amount of one quantity, there will also be zero amount of the second quantity.

These two points may not always be given as part of the set of data for a given real-world or mathematical situation, but they will always fall on the line that passes through the given data points.

Problem Set #9

1-3 Only

Remember from 5th and 6th grade...

For equations such as y = 3x – 2, the dependent variable is y. The value of y depends on the value chosen for x. Usually the dependent variable is isolated on one side of an equation. Formally, a dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value(s) of other variable(s).
