Question

dependent variable

• a variable whose value is ____ by another variable.
• it represents the \____\ or

esult\ that changes.

• usually represented by ___

constant of proportionality

• the ______ (k) is the special, ______ number that shows how two things are related when they change together.
• you can find it by dividing the \_\ value by the \_\ value (k = y/x),
• for example, if one can of soup costs $1.50, then $1.50 is the constant of proportionality.

direct variation

• a ______ graph that starts at the origin (0,0)
• this means that as x increases, y increases by the same factor(number), and as x decreases, y decreases proportionally.

Explanation:

Dependent Variable

• A variable whose value is determined by another variable.
• It represents the "outcome" or "result" that changes.
• Usually represented by 'y'

Constant of Proportionality

• The constant of proportionality (\(k\)) is the special, fixed number that shows how two things are related when they change together.
• You can find it by dividing the "dependent (y)" value by the "independent (x)" value (\(k = \frac{y}{x}\)).

Direct Variation

• A straight - line graph that starts at the origin \((0,0)\)
• This means that as \(x\) increases, \(y\) increases by the same factor (number), and as \(x\) decreases, \(y\) decreases proportionally.
