Negative Direction
Elementary SchoolMiddle School
Definition
A descriptor of data on a plot. Negative direction is usually describing a downward slope on a plot, where one value is decreasing and the other value is increasing or vice versa.
Worked examples
\(y = -2x + 5\)
As x increases, y decreases — the slope is negative and the line falls from left to right.
\(y = \frac{1}{x}\) for \(x > 0\)
As x increases, y decreases toward zero — this curve has negative direction in the first quadrant.
Common mistakes
- Negative direction means the y-values are negative → Negative direction means one variable decreases as the other increases Direction is about the relationship between variables, not the sign of the values themselves.
- A line with negative slope \(m = -3\) goes upward → A line with negative slope \(m = -3\) goes downward (negative direction) Negative slope always means the line falls from left to right.
- Points \((1,5)\) and \((3,2)\) show positive direction because both coordinates are positive → Those points show negative direction because y decreased as x increased Check whether y goes up or down as x increases, not whether the numbers are positive.
Where you'll use it next
You'll use negative direction when analyzing linear functions, interpreting scatter plots and correlation, studying inverse relationships in algebra, and describing rates of change in calculus.
