Astraight line on a graph indicates that there is a relationship between the dependent variable and the independent variable

A straight line on a graph indicates that there is a DIRECT or LINEAR relationship between the dependent variable and the independent variable

Explanation:

As we know that the equation of straight line is given as

here we know that

y = dependent variable

x = independent variable

So here we know that independent variable when directly depends on independent variable then the relation between them is plotted on the graph must be a straight line graph

so correct answer will be

A straight line on a graph indicates that there is a DIRECT or LINEAR relationship between the dependent variable and the independent variable

the chart show the masses and velocities of two colliding objects that stick together after a collision.
