Seven inches are equivalent to 17.78 cm. Find the equation converting length in cm to length in inches. What is the length in inches of a 96.2 cm bar?

17.8cm =7 in.

1cm = (7/17.78)in

96.2cm = 96.2 (7/17.78)in

96.2cm = 37.874 in

can this be graphed and how?

I = c/2.54 , where I is inches and c is cm

so when c = 96.2

I = 96.2/2.54 = 37.87

it can be graphed by having a horizontal axis called c for cm, and a vertical called I for inches.

since it is a straight line any two points will fix the line

I would use (0,0) and perhaps (2.54, 1) or (5.1, 2)
