Question

Explain how coordinates of a point on a graph relate to the dependent and independent variables of an equation.

Answer 1

Explanation:

If you're given (a, b) and are told that this represents a point on a graph, then a represents the independent variable and b the dependent one.

This stems from b = f(a), where 'f' is the name of a function.

Answer 2

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). ... In graphs with only positive values for x and y, the origin is in the lower-left corner.
