Question

the ______ is used to represent the independent variable on a graph.

○ x-axis

○ y-axis

○ z-axis

○ sine curve

Explanation:

In a typical graph (like a Cartesian coordinate system), the independent variable is plotted on the x - axis. The y - axis is for the dependent variable, the z - axis is used in 3 - D graphs (not relevant here for this basic question), and a sine curve is a type of graph, not an axis for representing variables. So the x - axis is used to represent the independent variable.

Answer:

A. x - axis
