Suppose f is a negative fraction. Then |f| is the absolute value of the fraction - the value disregarding the sign. The number is graphed at a distance of |f| to the left of the origin, the zero point.

All fractions can be labelled on a number line.
a correlation on a graph is when the line of best fit is positive, negative or none.
Write two fractions that the point on the number line represent
The trend of a graph is the slope of any line on the graph that indicated a positive or growth factor and/or a negative or decaying factor. If the slope goes negative, the graph's line will go down thus indicating decay. If the slope becomes positive, the graph's line will go up thus indicating growth.
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
