Question

A student is working on a project for which he records the revolutions per minute (rpm) for a small electric motor as he increases the voltage in a circuit. Here is the table showing the results:
Voltage
(volt) Motor Speed
(rpm)
0 0
1 25
2 50
3 75
4 100
Create a graph showing the relationship in the table. Think about the title, axis labels, and whether you need to connect the points with a line.

Answer 1

Answer:

See below ↓

Step-by-step explanation:

The relation is :

• Let y = Motor Speed and x = Voltage
• y = 25x

Title : Variation of Motor Speed with Applied Voltage

x-axis label : Voltage (volt)

y-axis label : Motor speed (rpm)

As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.
