Answer is on the attached graph
Using rate or slope of 1/4
Explanation: based on the information given, the ratio is $100:400#
This can be represented by 100 (y axis) over 400 (x axis)
To graph this, starting at zero, rise (up) 100 and run (over right) 400, place your first dot. Do this again from that dot, up 100 and over right 400 until you reach the end of your graph.
