Question

On a graph, which type of line shows a direct proportion? A. upwardly curved line B. downwardly curved line C. straight line D.jagged line

Answer 1

A straight line shows a direct proportion because each x-value has one y-value, and there is a correlation between the two values, not just random placement. Hope this helps! :)

Answer 2

Answer: Straight line

Explanation:

A straight line on the graph shows two factor that are represented on the x-axis and y-axis is directly proportional to each other.

In this condition the graph between these terms is a straight line. The term directly proportional states that if one factor is increasing then the other factor will also increase.

Example : Ohm's law, a straight line is formed when a graph is made between voltage and current as V=IR

Hence, the correct answer is option C
