Overview

Mathematical tools help economics describe relationships between variables in a clear and precise way. The two main tools covered are the slope of a straight line and the equation of a straight line. Slope shows how one variable changes when another variable changes, while the equation of a straight

Key Concepts

Statistical tools are used for

Statistical tools are used for the collection, organisation, presentation, analysis, and interpretation of data. Sample and census techniques are used

A curve is the graphic representation

A curve is the graphic representation of a functional relationship between two variables. A curve can be a straight line, convex, or concave depending

Slope is the ratio of change

Slope is the ratio of change in Y to change in X between two points of a curve. The formula is Slope = Change in Y / Change in X = ΔY/ΔX. This definit

A downward sloping straight line has

A downward sloping straight line has a negative slope. In the example, slope is -4, which means that when X rises by 1 unit, Y reduces by 4 units. Its

An upward sloping straight line has

An upward sloping straight line has a positive slope. In the example, Y increases by 8 units and X increases by 2 units, giving slope +4. Its equation
